A dense, scan-first view for the final hour before an interview. Each card gives you the answer shape, the trap to avoid, and the metric or debugging signal to mention.
Do not stop at DNS and HTTP. Include rendering, security, and Web Vitals.
Q002
V8 JavaScript Engine
Tiered execution
Answer Shape
V8 parses source, creates bytecode, runs Ignition, profiles hot paths, optimizes with TurboFan, and de-optimizes when assumptions fail.
Avoid Saying
Do not say JavaScript is only interpreted or TypeScript makes runtime faster.
Q003
Execution Context
Runtime environment
Answer Shape
Execution context contains lexical bindings, variable bindings, and this. Function calls create contexts that are pushed onto the call stack.
Avoid Saying
Do not say hoisting physically moves code.
Q004
Call Stack
Active execution
Answer Shape
The call stack tracks active frames. Function calls push frames; returns and thrown errors pop frames. Async waiting happens outside the stack.
Avoid Saying
Do not say async work stays on the stack while waiting.
Q005
Memory Heap
Reachability
Answer Shape
The heap stores objects and dynamic data. Garbage collection reclaims unreachable objects; leaks happen when unused objects remain reachable.
Avoid Saying
Do not say garbage collection prevents memory leaks.
Q006
Event Loop
Scheduling
Answer Shape
The event loop runs a task, drains microtasks after the stack clears, gives rendering a chance, then picks the next task.
Avoid Saying
Do not say async means parallel execution on the main thread.
Q007
Microtasks vs Macrotasks
Queue priority
Answer Shape
Promise callbacks and queueMicrotask are microtasks. Timers and user events are tasks. Microtasks drain before the next task and before rendering.
Avoid Saying
Do not treat promises as a background thread.
Q008
Critical Rendering Path
Pixels pipeline
Answer Shape
HTML builds DOM, CSS builds CSSOM, both form the render tree, then layout, paint, and composite produce pixels.
Avoid Saying
Do not ignore render-blocking CSS, parser-blocking scripts, or LCP priority.
Q009
DOM and CSSOM
Browser object models
Answer Shape
DOM represents document structure. CSSOM represents parsed style rules. The browser combines them to compute the render tree.
Avoid Saying
Do not say the DOM is what users see. Users see pixels after layout, paint, and compositing.
Q010
Layout, Reflow, Paint and Compositing
Rendering cost stages
Answer Shape
Layout calculates geometry, paint records visuals, and compositing assembles layers. Reflow is layout recalculation after a geometry-affecting change.
Avoid Saying
Do not call every rendering problem a repaint. Separate layout, paint, and composite costs.
Q011
Browser Storage
Client persistence choices
Answer Shape
Use Web Storage for small string data, IndexedDB for large structured data, Cache Storage for request/response caching, and cookies for server-visible state.
Avoid Saying
Do not store sensitive tokens in localStorage without discussing XSS risk.
Q012
Cookies and Sessions
Browser-managed request state
Answer Shape
Cookies are automatically sent with matching requests. HttpOnly blocks JS reads, Secure requires HTTPS, and SameSite controls cross-site sending.
Avoid Saying
Do not say HttpOnly prevents XSS; it only prevents cookie reads.
Q013
DOM Events and Event Delegation
Interaction flow
Answer Shape
Events move through capture, target, and bubble phases. Delegation attaches a listener to an ancestor and handles child events through target checks.
Avoid Saying
Do not confuse target with currentTarget or assume every event bubbles.
Q014
Script Loading
Discovery and execution
Answer Shape
Classic scripts block parsing, defer preserves order after parsing, async executes when ready, and module scripts are deferred by default.
Avoid Saying
Do not use async for ordered dependencies or preload every resource.
Q015
Web Workers
Main-thread protection
Answer Shape
Workers run JavaScript off the main thread and communicate with postMessage. They cannot directly access the DOM.
Avoid Saying
Do not move tiny work to workers without measuring message overhead.
Q016
Service Workers
Programmable request layer
Answer Shape
Service workers run separately from the page, intercept fetches after activation, and can serve cache, network, or offline fallbacks.
Avoid Saying
Do not treat service workers like normal workers or cache every response with one rule.
Q017
HTTP Caching
Freshness and validation
Answer Shape
Cache-Control defines storage and freshness. ETag and Last-Modified enable conditional requests that can return 304 without a body.
Avoid Saying
Do not confuse no-cache with no-store or put long immutable caching on HTML.
Q018
CORS
Browser read permission
Answer Shape
CORS lets servers opt in to cross-origin response reads. The browser enforces it with allow headers and preflight checks.
Avoid Saying
Do not call CORS authentication or try to fix every CORS issue only in React.
Q019
Fetch Lifecycle
Cancellation and correctness
Answer Shape
Fetch resolves on HTTP responses, rejects on network or abort failures, and needs response.ok checks plus AbortController for stale work.
Avoid Saying
Do not assume fetch rejects on 404 or let old search results overwrite newer state.
Q020
Realtime Transports
Direction and latency
Answer Shape
Polling pulls updates, SSE streams server-to-client events, and WebSockets provide bidirectional persistent messaging.
Avoid Saying
Do not choose WebSockets by default when SSE or polling satisfies the product need.
Q021
Frontend Observability
Real-user browser signals
Answer Shape
Collect browser performance, errors, resources, interactions, and custom marks with route, device, release, and privacy context.
Avoid Saying
Do not rely only on Lighthouse or collect telemetry without a debugging use case.
Q022
Core Web Vitals
Field attribution
Answer Shape
LCP measures loading, INP responsiveness, and CLS visual stability. Debug with field data, route context, release, and attribution.
Avoid Saying
Do not stop at metric names or rely only on lab scores.
Use semantic HTML, keyboard support, visible focus, labels, contrast, accessible errors, and careful ARIA.
Avoid Saying
Do not reduce accessibility to adding aria labels at the end.
Q029
Forms and Validation
Input lifecycle
Answer Shape
Good forms combine semantic controls, client feedback, server validation, duplicate protection, accessible errors, and recovery.
Avoid Saying
Do not trust client validation or clear input after failed requests.
Q030
Responsive Media
Right asset delivery
Answer Shape
Use responsive candidates, dimensions, modern formats, CDN delivery, lazy loading for non-critical media, and priority for LCP.
Avoid Saying
Do not ship one huge image to every device or lazy-load the LCP image.
Q031
I18n and L10n
Global-ready UI
Answer Shape
Use message catalogs, plural rules, locale formatting, RTL support, fallbacks, and text expansion testing.
Avoid Saying
Do not concatenate translated strings or assume English layout.
Q032
URL State
Shareable views
Answer Shape
Put shareable, reloadable, restorable view state in the URL and use history updates that preserve back-button expectations.
Avoid Saying
Do not hide important filters only in memory or push history on every keystroke.
Q033
Back Forward Cache
Restored navigation
Answer Shape
bfcache stores a frozen page snapshot for instant back/forward navigation when the page avoids blockers.
Avoid Saying
Do not add unload handlers casually or assume every visit is a fresh load.
Q034
File Upload UX
Reliable file workflows
Answer Shape
Use native input fallback, validation, progress, cancellation, retry, accessible drop zones, and server-side enforcement.
Avoid Saying
Do not trust client validation or make drag-and-drop the only path.
Q035
Capability APIs
Permission-aware UX
Answer Shape
Clipboard, drag, and permission APIs need secure contexts, user gestures, feature detection, fallback UX, and privacy care.
Avoid Saying
Do not assume capability APIs always work or that permission is guaranteed.
Q036
Motion Performance
Responsive motion
Answer Shape
Use CSS transitions, keyframes, or WAAPI as needed; prefer transform and opacity; respect reduced motion.
Avoid Saying
Do not animate layout-heavy properties or ignore interruption.
Q037
CSS Architecture
Predictable styling
Answer Shape
Manage cascade, layers, specificity, tokens, component boundaries, and override rules to avoid styling fights.
Avoid Saying
Do not solve every conflict with !important or high-specificity selectors.
Q038
Flexbox and Grid
Responsive layout
Answer Shape
Use flexbox for one-dimensional layout, grid for two-dimensional layout, and intrinsic constraints for resilient responsive UI.
Avoid Saying
Do not build fixed layouts that break with long text, zoom, or localization.
Q039
Design Systems
Shared UI infrastructure
Answer Shape
Design systems combine tokens, component contracts, accessibility rules, documentation, and governance.
Avoid Saying
Do not treat a component library alone as a design system.
Q040
Theming
Preference-aware tokens
Answer Shape
Use semantic tokens, CSS variables, system preference, user override, persistence, and contrast checks.
Avoid Saying
Do not invert colors mechanically or ignore dark-mode states.
Q041
Client Data Caching
Fresh server state
Answer Shape
Define cache keys, stale time, refetch triggers, invalidation, optimistic updates, rollback, and error recovery.
Avoid Saying
Do not treat server state like local UI state.
Q042
State Management
State ownership
Answer Shape
Place state by owner and lifetime: local UI, server cache, URL, derived values, persistent settings, or global app state.
Avoid Saying
Do not duplicate sources of truth or put every value in a global store.
Q043
Error Boundaries
Graceful failure
Answer Shape
Use boundaries, route fallbacks, async error states, retry UX, and logging so one failure does not blank the app.
Avoid Saying
Do not use one global error screen for every failure.
Q044
Testing Strategy
Confidence layers
Answer Shape
Use unit, integration, E2E, accessibility, visual, contract, and monitoring checks according to user risk.
Avoid Saying
Do not chase snapshots while missing critical user flows.
Q045
Playwright
Real browser flows
Answer Shape
Use resilient locators, isolated data, traces, screenshots, and focused critical journeys for trustworthy E2E tests.
Avoid Saying
Do not rely on brittle selectors, sleeps, or giant all-in-one tests.
Q046
TypeScript Basics
Static contracts
Answer Shape
TypeScript models compile-time contracts, improves refactors, and catches invalid shapes, but runtime data still needs validation.
Avoid Saying
Do not claim TypeScript validates external JSON at runtime.
Q047
Type Narrowing
Safe branching
Answer Shape
Use narrowing and discriminated unions to model valid UI states and protect refactors with exhaustive checks.
Avoid Saying
Do not model every state with optional fields.
Q048
Generics
Typed reuse
Answer Shape
Generics preserve relationships between inputs and outputs, while utility types transform reusable contracts.
Avoid Saying
Do not over-genericize code until simple logic becomes unreadable.
Q049
Runtime Validation
Trust boundaries
Answer Shape
Validate external data at runtime because TypeScript types are erased and cannot prove JSON shape.
Avoid Saying
Do not assign response.json directly to a trusted domain type.
Q050
React Rendering
Render vs commit
Answer Shape
React renders components to compute UI, reconciles trees, and commits necessary host changes; keys preserve identity.
Avoid Saying
Do not say React replaces the whole DOM on every state update.
Q051
React State Flow
Ownership
Answer Shape
Props pass data down, state owns changing local values, and clear source-of-truth choices prevent stale UI.
Avoid Saying
Do not copy props into state without a synchronization reason.
Q052
React Effects
External sync
Answer Shape
Effects synchronize React with external systems and need correct dependencies, cleanup, and stale async handling.
Avoid Saying
Do not use effects for pure derived values.
Q053
React Memoization
Measured optimization
Answer Shape
Use memo, useMemo, and useCallback when profiler evidence shows meaningful render or calculation cost.
Avoid Saying
Do not wrap everything in memoization without measuring.
Q054
React Forms
Input ownership
Answer Shape
Controlled inputs are owned by React state; uncontrolled inputs are owned by the DOM and read when needed.
Avoid Saying
Do not force every field into React state when native behavior is enough.
Q055
React Composition
Reusable UI contracts
Answer Shape
Use children, slots, compound components, render props, and controlled APIs to keep reusable UI flexible.
Avoid Saying
Do not create giant boolean-prop configuration components.
Q056
React Context
Scoped shared values
Answer Shape
Context shares values in a subtree; keep provider scope tight and values stable to avoid broad re-renders.
Avoid Saying
Do not put frequently changing large state in one global context.
Q057
React Profiling
Evidence-based fixes
Answer Shape
Use React Profiler and browser traces to separate render cost, commit cost, layout, paint, and data processing.
Avoid Saying
Do not optimize React before measuring the real bottleneck.
Q058
Suspense and Streaming
Async boundaries
Answer Shape
Suspense coordinates loading at boundaries; streaming progressively reveals useful UI before everything is ready.
Avoid Saying
Do not use one global spinner for every async operation.
Q059
Next.js App Router
Route architecture
Answer Shape
App Router uses route segments, layouts, pages, loading/error files, Server Components, and intentional Client Components.
Avoid Saying
Do not mark broad layouts as client components without need.
Q060
Rendering Strategies
Freshness vs speed
Answer Shape
SSR is per request, SSG is build-time, ISR balances static speed with freshness, and hydration adds client cost.
Avoid Saying
Do not choose SSR for everything or ignore hydration cost.
Q061
SEO Metadata
Discoverability
Answer Shape
Use crawlable semantic content, metadata, canonical URLs, social previews, structured data, sitemap, and performance.
Avoid Saying
Do not treat SEO as only title tags.
Q062
Frontend Auth
Session lifecycle
Answer Shape
Handle login, restore, refresh, protected routes, storage trade-offs, logout cleanup, and secure error states.
Avoid Saying
Do not store sensitive long-lived tokens in JS-readable storage casually.
Q063
Authorization
Capability-aware UI
Answer Shape
Frontend reflects capabilities, while the backend enforces authorization. Prefer capability checks over scattered role checks.
Avoid Saying
Do not rely on hidden buttons as security.
Q064
Micro Frontends
Independent delivery
Answer Shape
Micro frontends split ownership and deployment, but add integration, consistency, performance, and testing overhead.
Avoid Saying
Do not choose micro frontends only because the codebase is large.
Q065
Module Federation
Runtime composition
Answer Shape
A host loads remote modules at runtime; shared dependencies, compatibility, fallbacks, and monitoring are critical.
Avoid Saying
Do not share every dependency blindly or ignore remote loading failure.
Q066
Monorepos
Package ownership
Answer Shape
Monorepos need clear package boundaries, ownership, dependency rules, build caching, and affected tests.
Avoid Saying
Do not let shared packages become dumping grounds.
Q067
Frontend CI/CD
Safe releases
Answer Shape
CI/CD validates, builds, previews, deploys, monitors, and supports rollback with traceable release metadata.
Avoid Saying
Do not treat deployment success as release success.
Q068
Docker Basics
Portable runtime
Answer Shape
Docker images package runtime dependencies; containers run images; frontend teams must separate public build config from runtime secrets.
Avoid Saying
Do not bake secrets into client bundles or containers.
Q069
CDN and Edge
Global asset delivery
Answer Shape
CDNs cache assets near users; hashed assets can be immutable, while HTML and personalized data need careful freshness rules.
Avoid Saying
Do not cache personalized data or delete old chunks casually.
Q070
Feature Flags
Controlled rollout
Answer Shape
Flags decouple deploy from release and support targeting, experiments, progressive rollout, kill switches, and cleanup.
Avoid Saying
Do not leave stale flags forever or use client flags as authorization.
Q071
Dashboard Design
Complex app architecture
Answer Shape
Design dashboards from users, data freshness, permissions, URL filters, caching, charts, tables, performance, and telemetry.
Avoid Saying
Do not start with components before clarifying data and scale.
Q072
Data Grids
Dense data UX
Answer Shape
Use server/client operation rules, virtualization, accessible navigation, stable columns, URL state, and measured rendering.
Avoid Saying
Do not render thousands of rows without measuring DOM and interaction cost.
Q073
Offline Sync
Resilient distributed UX
Answer Shape
Offline-first needs local persistence, queued writes, idempotency, retry, conflict policy, and visible sync status.
Avoid Saying
Do not pretend offline sync is just localStorage plus retry.
Q074
Trade-Off Communication
Decision clarity
Answer Shape
Explain context, options, constraints, trade-offs, recommendation, rollout, metric, and fallback.
Avoid Saying
Do not present only one option or hide uncertainty.
Q075
Interview Storytelling
Evidence-based stories
Answer Shape
Use context, constraints, action, trade-off, result, and reflection with measurable impact and honest ownership.
Avoid Saying
Do not list technologies without explaining decisions and impact.
