1. What is AngularJS?
Why you might get asked this:
Interviewers open with this foundational query to check if you can articulate the framework’s essence, its single-page application focus, and how it differs from plain JavaScript or newer Angular versions. A crisp explanation shows you understand the historical context of angularjs 1 interview questions and can justify why many enterprises still rely on AngularJS for mission-critical apps. Conveying this clearly sets the tone for deeper technical discussion.
How to answer:
Start by identifying AngularJS as Google’s original open-source JavaScript framework designed for dynamic single-page applications. Mention core features like two-way data binding, dependency injection, MVC pattern implementation, and declarative HTML with directives. Briefly contrast it with vanilla JS and explain its role in simplifying complex UI logic. Wrap by noting community adoption and current maintenance considerations to display awareness of legacy support.
Example answer:
“In simple terms, AngularJS is Google’s first-generation framework for building single-page web apps. It lets you extend HTML with directives, bind data in both directions so the view and the model stay in sync, and inject dependencies to keep code modular. I first used AngularJS when re-working a dashboard that previously relied on jQuery spaghetti code; moving to AngularJS cut our update logic by half because the view automatically refreshed as the model changed. Even though newer frameworks exist, many fintech and government portals still rely on AngularJS, so knowing how to stabilize and gradually migrate those apps is a valuable skill the team is looking for.”
2. What is the difference between the DOM and the BOM in AngularJS?
Why you might get asked this:
Employers want proof that you can distinguish browser APIs from document manipulation. This angularjs 1 interview question uncovers whether you can select the correct service ($document vs. $window) and avoid unintended side effects when accessing global objects. Misunderstanding the DOM/BOM boundary often leads to memory leaks or cross-browser glitches, so interviewers dig here to protect their production code.
How to answer:
Explain that the DOM (Document Object Model) represents the page’s structured content—elements, attributes, and text—while the BOM (Browser Object Model) encapsulates browser-specific objects like window, navigator, and history. In AngularJS, you typically interact with the DOM via directives or the $document service and with the BOM via $window. Highlight best practices: wrap direct calls in services for testability and avoid manipulating the DOM in controllers.
Example answer:
“I like to think of the DOM as the page itself and the BOM as the browser around it. If I need to hide a sidebar based on screen width, I’d inject $window to watch resize events—that’s BOM territory. But if I’m adding an aria-label to improve accessibility, I’d write a directive that tweaks the element through $document—that’s pure DOM. Keeping those roles separate helped me fix a stubborn IE11 memory leak at my last job; controllers were touching window directly instead of using $window, so unit tests never caught the bug. Splitting DOM and BOM concerns made the code cleaner and far easier to mock during testing.”
3. What are three ways you can communicate between application modules?
Why you might get asked this:
Modular architecture is key to maintainable AngularJS apps. Interviewers pose this angularjs 1 interview question to assess if you understand broadcasting, shared services, and $rootScope usage—and when each is appropriate. They check for awareness of performance trade-offs and the need to avoid tight coupling. Proving mastery shows you can design scalable feature sets that won’t break as the app grows.
How to answer:
State the three primary techniques: 1) using $emit, $broadcast, and $on events; 2) storing shared data on $rootScope; and 3) exchanging data through singleton services or factories. Describe scenarios: events for loosely coupled communication, shared services for persistent data, and $rootScope for quick global flags (though sparingly, to prevent clutter). Emphasize testing and maintainability.
Example answer:
“In practice, I favor services because they centralize state. For example, our cartService held item counts so any module could update or display totals. If I only need a one-time ping-pong, I use $scope.$broadcast from a parent down or $emit upward—like notifying a header component when a language switch occurs. $rootScope is my last resort, reserved for app-wide settings such as ‘maintenanceMode.’ In a recent release we replaced eight $rootScope flags with a configService and cut our watcher count by 30 percent, which solved a performance dip that QA had flagged.”
4. Explain two-way data binding in AngularJS.
Why you might get asked this:
Two-way binding is core to AngularJS’s appeal. This angularjs 1 interview question verifies that you grasp how the digest cycle synchronizes model and view. Interviewers listen for understanding of $watch mechanics, performance implications, and how binding differentiates AngularJS from libraries like React (one-way by default). They want reassurance you can optimize binding when large watcher lists threaten speed.
How to answer:
Define two-way binding: any change to the model updates the view and vice versa. Clarify that AngularJS accomplishes this by adding watchers to scope properties and running digest cycles to check for changes. Note pros (rapid UI development) and cons (watcher overhead). Mention strategies like one-time binding (:: syntax) or ng-model-options to limit updates.
Example answer:
“Two-way binding felt magical the first time I typed ng-model='user.name' and watched the header update as I typed. Under the hood, AngularJS registers a watcher on user.name; during each digest cycle, it compares the old and new values and refreshes the DOM if there’s a mismatch. On a recent analytics dashboard we noticed frame drops because a table with 8,000 rows created thousands of watchers. We switched to one-time binding for static data and used ng-model-options with debounce on the search bar. End result: smoother scrolling, fewer digest iterations, and the same declarative code style that makes AngularJS productive.”
5. What is the scope hierarchy in AngularJS?
Why you might get asked this:
Correctly navigating the scope tree prevents variable shadowing and unwanted leaks. This angularjs 1 interview question ensures you can locate data sources, debug prototypal inheritance issues, and reason about performance. Interviewers look for awareness of $rootScope as the ancestor and how child scopes inherit but can’t overwrite primitives without creating new instances.
How to answer:
Explain that each AngularJS app has one $rootScope at the top, with child scopes created by directives (ng-repeat, ng-controller, isolate scopes). Scopes form a prototypal inheritance chain mirroring the DOM. Variables flow downward; lookups bubble up until found. Stress best practices: keep global data minimal, use dot notation (vm.user.name) to avoid primitive shadowing, and destroy orphaned scopes to avert memory bloat.
Example answer:
“I picture scopes like nested folders: the root is C:\ and every ng-controller adds another sub-directory. When I bind user.firstName in a child, AngularJS first checks that folder; if not found, it climbs up until it hits the root. That’s why using primitives directly can backfire—you end up shadowing. On a CRM project, the edit form wouldn’t save because firstName on the child scope masked the parent object, so updates never propagated. Moving to customer.firstName solved the issue and clarified intent for new team members.”
6. Define Scope in AngularJS.
Why you might get asked this:
Crystal-clear definition skills show communication prowess. This angularjs 1 interview question asks you to distill scope’s role as the glue between view and controller, highlighting responsibilities like event propagation and lifecycle management. A concise yet thorough definition demonstrates you can mentor juniors and write documentation.
How to answer:
State that a scope is an object that binds the model to the view, tracks expressions, and provides context for functions. Mention its prototypal relationship, ability to emit/broadcast events, and tie-in with the digest cycle. Note differences between $scope, controllerAs syntax, and isolate scope for reusable components.
Example answer:
“Scope is the middleman between HTML and JavaScript in AngularJS. It holds the page’s live data, exposes methods the view can call, and registers watchers so updates show instantly. Picture it as a backstage runner passing messages between the script and the set. When I refactor legacy controllers, I prefer controllerAs to reduce direct $scope usage, but I still rely on $scope.$on to listen for global events like logout. Understanding scope let me cut 200 lines of redundant glue code in our order-entry module.”
7. What are services in AngularJS?
Why you might get asked this:
Services keep code modular and testable. This angularjs 1 interview question checks if you know that services are singletons, how they differ from factories, and when to leverage them for cross-controller state. Showing best practices in dependency injection reassures teams that you won’t litter $rootScope with data.
How to answer:
Describe services as reusable, singleton objects that encapsulate business logic or shared state. Mention that AngularJS instantiates them once and injects where needed. Explain typical use cases: RESTful calls, shared caching, utility helpers. Stress advantages: easy mocking during tests, separation of concerns, and improved reusability.
Example answer:
“In my last SaaS project, an authService handled login status, token refresh, and role checks. Because AngularJS created just one instance, every controller had a consistent view of authentication. We also stubbed the service in unit tests to simulate guest or admin flows, speeding our CI pipeline. This pattern of packaging logic in services keeps controllers lean and makes onboarding easier for new hires.”
8. What is the difference between a factory and a service?
Why you might get asked this:
Teams want developers who choose the right provider pattern. This angularjs 1 interview question verifies understanding of AngularJS’s DI mechanics and ensures you can read legacy code that mixes factories, services, and providers. Explaining the nuances reflects depth.
How to answer:
Clarify that both return singletons, but factories return the value of a function, whereas services are instantiated with new and attach properties to ‘this’. Factories offer more flexibility for creating objects or closures; services are simpler when you need a plain object. Summarize syntax differences and mention testing implications.
Example answer:
“I reach for a factory when I need a private scope or want to expose a function that generates different objects. For example, our chartFactory produced new D3 wrappers on demand. When I just need one global logger, I register it as a service—AngularJS does ‘new’ for me and I can attach log() to ‘this’. Choosing the right style keeps the codebase consistent and reduces onboarding questions.”
9. Explain the concept of dependency injection.
Why you might get asked this:
Dependency injection (DI) underpins AngularJS architecture. This angularjs 1 interview question tests whether you can harness DI for modular design, testing, and mocking. Interviewers look for awareness of minification-safe annotations and default resolution order.
How to answer:
Define DI as a pattern where components declare dependencies and the framework supplies them, promoting loose coupling. Describe AngularJS’s injector, the array syntax for minification safety, and the ability to override services in tests. Emphasize benefits: easier testing, decoupled modules, configurable implementations.
Example answer:
“Instead of a controller doing new AuthService(), AngularJS injects authService automatically. In our payment flow we swapped the real stripeService with a mock in unit tests, proving refunds worked without hitting the API. That zero-config swap is why DI is my favorite AngularJS feature—it keeps components focused on their job instead of wiring.”
10. What are directives in AngularJS?
Why you might get asked this:
Directives power AngularJS’s declarative UI. This angularjs 1 interview question ensures you can author reusable components, manipulate the DOM responsibly, and select proper directive types (attribute, element, class, comment). Demonstrating directive expertise reveals whether you can abstract complexity into maintainable building blocks.
How to answer:
Define directives as markers on DOM elements that tell AngularJS’s compiler to attach specific behavior. Mention built-in examples (ng-model, ng-repeat) and custom directives for widgets. Outline key options: restrict, template, scope, link, compile. Stress testability and separation of concerns.
Example answer:
“When our marketing team wanted a reusable star-rating widget, I wrote a starRating directive with isolate scope and a template of clickable icons. The link function handled hover events, and we used ng-model to sync with the parent form. Adding ratings elsewhere became one HTML tag—way easier than copying event handlers. That’s the real power of directives.”
11. What is the purpose of the $compile service?
Why you might get asked this:
$compile is advanced but vital. This angularjs 1 interview question filters for developers who can build dynamic templates, particularly in white-label products. Interviewers look for knowledge of compile vs. link phase and performance implications.
How to answer:
Explain that $compile takes HTML strings or DOM and returns a linking function that binds scope, allowing dynamic template generation. Use cases: CMS-driven content, directive factories. Mention security: sanitize unknown HTML, limit compile calls for speed.
Example answer:
“On a CMS project, editors stored HTML in a database. We fetched it, sanitized for XSS, then used $compile to bind AngularJS expressions inside that content. That let marketing update banners without dev help, yet data like {{price}} still updated live. Understanding $compile saved us from a rewrite and kept performance solid by caching compiled templates.”
12. How do you handle errors in AngularJS?
Why you might get asked this:
Robust apps need graceful degradation. This angularjs 1 interview question uncovers strategies for $exceptionHandler, promise rejections, and user messaging. Interviewers value proactive logging and recovery plans.
How to answer:
Discuss overriding $exceptionHandler to log to external services, adding .catch on promises, broadcasting error events, and showing UI notifications. Note distinctions between synchronous and async errors and strategies like retry logic or fallback routes.
Example answer:
“We wrapped $exceptionHandler to push stack traces to Sentry with user context. For async calls, each $http promise had a .catch that triggered our toastService so users saw friendly messages. During a payment outage, retries with exponential backoff and clear alerts kept churn low and helped support triage issues quickly.”
13. Explain the concept of a digest cycle.
Why you might get asked this:
Performance hinges on digest understanding. This angularjs 1 interview question tells a hiring team if you can optimize watchers, debug infinite loops, and use $apply wisely. It separates casual users from power users.
How to answer:
Describe the digest as an internal process where AngularJS checks all watchers for changes, repeating until stable or 10 iterations (throwing $rootScope:infdig). Mention triggers (events, $http, $apply) and optimization tactics: fewer watchers, $scope.$evalAsync, one-time bindings.
Example answer:
“Think of the digest like a referee making sure the scoreboards match. Each watcher is inspected; if a change is found, AngularJS keeps looping until nothing changes or it hits the limit. We once had a directive updating a bound value inside a watcher, causing an infinite digest. Detecting it via the error log led us to move that logic into $timeout, breaking the loop and cutting CPU usage by 40 percent.”
14. What is the difference between $scope.$apply() and $digest()?
Why you might get asked this:
Understanding manual digest triggers is crucial when integrating third-party libraries. This angularjs 1 interview question reveals whether you can safely invoke change detection from outside AngularJS.
How to answer:
Explain that $apply runs a function then initiates a digest from the $rootScope, covering the whole tree, while $digest only checks the current scope and its children. $apply is used when external callbacks modify scope. Warn against overusing $apply for performance reasons.
Example answer:
“When integrating a jQuery datepicker, its select callback ran outside AngularJS. Wrapping the model update in $scope.$apply ensured the view updated. If I only needed to refresh a small isolated widget, I could call $digest on that local scope, but doing so app-wide would miss other watchers. Picking the right one keeps updates consistent without unnecessary work.”
15. How do you implement routing in AngularJS?
Why you might get asked this:
Routing shapes the user journey. This angularjs 1 interview question assesses whether you know ngRoute vs. ui-router, resolve blocks, and lazy loading. It gauges architectural planning skills.
How to answer:
Outline using $routeProvider (ngRoute) or $stateProvider (ui-router) to map URLs to templates/controllers. Describe configuring fallback routes, nested states, and route resolves for preloading data. Note best practices: avoid heavy controllers, use component routers for future migration.
Example answer:
“We used ui-router because its nested states mirrored our product hierarchy. For /orders/:id we set up a resolve that fetched order details before showing the page, preventing flicker. A default ** route redirected to /dashboard. This structure let marketing add new promo states with minimal dev cycles, and deep linking improved SEO.”
16. What is the purpose of the $http service?
Why you might get asked this:
External data drives apps. This angularjs 1 interview question ensures you can perform CRUD with RESTful APIs, handle promises, and intercept requests for auth tokens.
How to answer:
Describe $http as a wrapper around XMLHttpRequest/Fetch, offering get, post, put, delete methods, returning promises. Highlight interceptors for headers, timeouts, caching, and error handling.
Example answer:
“Our $http interceptor attached JWT headers and logged response times. When an endpoint returned 401, it broadcast a re-login event. Using $http kept code DRY and portable; we swapped endpoints during a backend migration by changing a single baseUrl constant.”
17. Explain the concept of a controller in AngularJS.
Why you might get asked this:
Controllers bridge data and view. This angularjs 1 interview question checks whether you can keep controllers thin and delegate logic appropriately.
How to answer:
Define controllers as constructors initialized with a scope, responsible for setting up initial model state and exposing functions. Emphasize that heavy logic should live in services; controllers should avoid DOM manipulation.
Example answer:
“My InvoiceCtrl pulled totals from billingService and exposed saveDraft(). All tax calculations lived in billingService so we could reuse them in a mobile app. This kept the controller under 80 lines and facilitated unit testing with mocked services.”
18. What are the benefits of using AngularJS?
Why you might get asked this:
Employers want to see value articulation. This angularjs 1 interview question assesses whether you appreciate two-way binding, DI, testing tools, and community resources.
How to answer:
List benefits: rapid development via data binding, modular structure, reusable directives, built-in testing with Karma+Jasmine, large plugin ecosystem, and gradual migration paths.
Example answer:
“In my experience, AngularJS’s sweet spot is speed to prototype. We delivered an MVP in six weeks thanks to ng-repeat, form validation, and $http. Auto-updating views cut boilerplate in half, and unit tests gave the product owner confidence to iterate swiftly.”
19. How do you handle cross-browser compatibility issues?
Why you might get asked this:
Legacy support matters. This angularjs 1 interview question reveals knowledge of $document, $window, and polyfills.
How to answer:
Discuss feature detection, AngularJS’s jQLite abstraction, conditional polyfills, and CSS prefixes. Mention using ng-touch, flexbox fallbacks, and e2e tests across browsers.
Example answer:
“To support IE11 we polyfilled Promise and classList, verified swipe gestures with ng-touch, and avoided flex gaps. Using $window instead of window let us stub dimensions in unit tests and kept Safari quirks isolated.”
20. Explain the concept of a filter in AngularJS.
Why you might get asked this:
Filters polish UI data. This angularjs 1 interview question tests if you can format and chain filters efficiently.
How to answer:
Define filters as functions that transform data in templates or controllers, used via the pipe symbol. Mention built-in (currency, date) and custom filters, and note they’re stateless.
Example answer:
“We built a phoneMask filter that displayed numbers as (123) 456-7890 without altering the model. Marketing loved that we could chain phoneMask | uppercase right in the template, keeping controllers clean.”
21. What is the difference between a promise and a callback?
Why you might get asked this:
Async mastery is essential. This angularjs 1 interview question asks you to compare control-flow paradigms.
How to answer:
State that callbacks execute once context is ready but risk pyramid of doom, while promises represent future values and allow chaining and centralized error handling. Explain $q in AngularJS.
Example answer:
“When uploading files, we nested three callbacks and debugging became a nightmare. Rewriting with $q promisified the flow: upload().then(resize).then(save).catch(alert). That single error handler simplified maintenance and reduced bugs.”
22. How do you optimize the performance of an AngularJS application?
Why you might get asked this:
Speed equals user satisfaction. This angularjs 1 interview question checks your toolkit: digest tuning, lazy loading, and track by.
How to answer:
Mention reducing watchers, using one-time binding, track by in ng-repeat, debouncing events, and minifying assets. Discuss ahead-of-time template caching and ng-animate toggles.
Example answer:
“We profiled with Batarang, found 12,000 watchers, and cut 40 percent by adding ::. Then we switched heavy modals to ui-bootstrap’s on-demand loading, dropping initial payload by 300 KB and slashing time-to-interactive.”
23. Explain a directive’s compile function vs. link function.
Why you might get asked this:
Deep directive knowledge signals seniority. This angularjs 1 interview question ensures you know lifecycle phases.
How to answer:
Compile runs once per template to transform DOM; link runs per instance and wires up scope, events. Use compile for DOM manipulation requiring template changes and link for post-compile logic.
Example answer:
“Our markdown directive moved code highlight logic to compile so we parsed once per template, then link bound the preview toggle per element. This reduced processing time on list pages with 100 messages.”
24. What is the role of the $location service?
Why you might get asked this:
Navigation control is vital. This angularjs 1 interview question checks how you read/set URLs, query params, and browser history.
How to answer:
Explain $location as a wrapper around window.location, offering path(), search(), hash(), url(), and event listeners. Emphasize deep linking and SEO.
Example answer:
“To share filtered reports, we updated $location.search({status:'open'}) whenever the user toggled filters, so copying the URL reproduced the state after paste—making QA and customers happy.”
25. How do you handle asynchronous data in AngularJS?
Why you might get asked this:
Async data is everywhere. This angularjs 1 interview question looks for promise usage and race-condition handling.
How to answer:
Discuss $http, $q.all, $timeout, $interval, and digest concerns. Stress error chains and loading states.
Example answer:
“In our dashboard we fired three API calls in parallel with $q.all and showed a spinner bound to isLoading. The promise chain hid the loader only after all responses arrived or any failed, giving users clear feedback.”
26. Explain how to use $q for promises.
Why you might get asked this:
Shows deeper async control. This angularjs 1 interview question tests creating custom deferred objects.
How to answer:
Explain $q.defer, resolve, reject, notify, and returning promise. Mention wrapping callback APIs.
Example answer:
“We had a legacy WebSocket callback. Wrapping it in $q.defer let controllers consume socketService.connect().then(onOpen).catch(onError) just like $http, unifying our code style.”
27. What is the purpose of the $anchorScroll service?
Why you might get asked this:
UX touches matter. This angularjs 1 interview question gauges your thoroughness in user navigation.
How to answer:
State that $anchorScroll scrolls to element IDs tied to $location.hash(), useful in single-page docs. Mention customizing offset for fixed headers.
Example answer:
“On our FAQ page, clicking a sidebar link updated $location.hash and we called $anchorScroll, smoothly scrolling beneath the sticky navbar. Users reported easier navigation and session time increased 15 percent.”
28. How do you implement authentication in an AngularJS application?
Why you might get asked this:
Security is non-negotiable. This angularjs 1 interview question checks token storage, route guards, and refresh workflows.
How to answer:
Describe token-based auth via $http interceptors, storing JWT in HttpOnly cookies or localStorage, protecting routes with resolves, and refreshing tokens. Mention CSRF mitigation and logout flow.
Example answer:
“We stored JWT in a secure cookie, added an authInterceptor to attach it, and defined a route resolve that rejected unauthenticated access by redirecting to /login. Tokens refreshed via a silent iframe, so users rarely saw the login screen again, yet sessions stayed secure.”
29. Explain the concept of nested scopes.
Why you might get asked this:
Nested scope understanding prevents bugs. This angularjs 1 interview question evaluates how you structure components.
How to answer:
Explain that child scopes inherit from parents but primitives can shadow. Mention isolate scopes and transclusion when writing directives.
Example answer:
“In a tabbed widget, each tab directive had an isolate scope to avoid polluting the parent form, yet the tabsManager used require:^tabs to register each child. This compartmentalization kept features independent while enabling coordinated behavior.”
30. How do you debug an AngularJS application?
Why you might get asked this:
Effective debugging saves time. This angularjs 1 interview question tests tool familiarity and systematic thinking.
How to answer:
Discuss browser DevTools, Batarang, console logs inside $watch, AngularJS built-in debugInfoEnabled, and mocking in unit tests. Emphasize reproducing issues and binary search.
Example answer:
“My go-to flow starts with Chrome DevTools’ Sources tab for breakpoints, then I use angular.reloadWithDebugInfo() to inspect scopes in Elements. Batarang helps visualize watchers. On one project, a stray digest loop only occurred after 18 clicks—recording DevTools Performance traces narrowed it to a directive misuse, saving days of guesswork.”
