Practice frontend the way interviews actually work

FrontendAtlas is built to make you interview-ready faster by turning prep into repeatable practice loops.

What you do here:
- Solve realistic coding tasks with starter code + fast feedback (preview/tests)
- Learn core concepts in a way you can actually explain in interviews
- Practice front-end system design by making tradeoffs, not memorizing buzzwords

If you want “less reading, more doing” — this is the workflow.

It’s all in the browser — no setup tax.

Open the app → pick a task → code immediately.
No local project, no dependency hell, no “works on my machine”.

Desktop/laptop is recommended so you can use the editor/preview layout efficiently.

Best experience on modern desktop browsers:
- Chrome / Edge (top pick for speed + compatibility)
- Safari
- Firefox

Mobile/tablet works for reading and browsing, but serious practice is designed for desktop (editor + preview + checks).

You’ll practice the three things interviews actually test:

1) Coding tasks
Build/modify real UI and logic with starter code, then validate with preview/tests.

2) Concept questions
Short prompts that force clean mental models (the kind you can explain under pressure).

3) Front-end system design
Architecture prompts focused on constraints + tradeoffs (how seniors think).

Coverage is designed to match real job requirements:
- JavaScript / TypeScript fundamentals (async, closures, DOM, performance, etc.)
- HTML / CSS (layout, responsive UI, practical accessibility basics)
- React / Angular / Vue (component patterns, state, rendering, performance)
- Front-End System Design track (architecture and tradeoffs)

So you can prep for “framework interview” and “real-world frontend” at the same time.

Everything is structured to reduce decision fatigue and keep you consistent.

You can filter/sort by:
- Technology (JS/TS, HTML/CSS, React, Angular, Vue, System Design)
- Difficulty (ramp up without getting stuck or bored)
- Tags (the exact skill being tested: event delegation, memoization, layout, state, etc.)

This makes it easy to build a weekly plan: pick a focus → grind a tight set → level up.

Yes — many tasks include solutions and detailed explanations, and more are added over time.

When available, solutions focus on what matters in interviews:
- a clean baseline implementation
- edge cases + common mistakes
- tradeoffs between approaches (when it’s not just “one right answer”)

Some prompts are intentionally open-ended to mirror real interview discussion.

Yes — many tasks have live preview so you can iterate fast and see what you’re building immediately.

This is ideal for HTML/CSS and UI work where “correct” is visual.

If preview isn’t the right signal (pure logic), the task uses checks/tests instead — so you still get clear pass/fail feedback.

Yes — tasks that can be validated deterministically include checks/tests (common for JS/TS).

This helps you practice like a professional workflow:
write → run checks → fix edge cases → ship.

HTML/CSS tasks typically rely on live preview first, because visuals are the primary correctness signal.

Yes — your work is saved locally in your browser so you don’t lose progress mid-practice.

Why this matters:
- You can do short sessions (even 15–30 min) and continue later
- Your drafts stay private on your device by default

You can also reset any task back to the starter whenever you want to re-practice from scratch.

Premium is for people who want the fastest path to results.

Typically, it unlocks:
- Premium question sets and deeper practice content
- More guided solutions/explanations where available
- Ongoing content updates while your plan is active

If you’re practicing consistently, Premium mainly saves you time: less hunting, more reps.

Yes.

If you think you were charged incorrectly or something isn’t working, email support@frontendatlas.com and we’ll help.

Email support@frontendatlas.com with:
- steps to reproduce (what you clicked / expected / got)
- browser + OS version
- the page URL or question id

A screenshot or short screen recording speeds up fixes a lot.

Quick checklist (most issues are one of these):

- Re-check billing details (name, address, ZIP/postal code if required)
- Try a different card (or a virtual card)
- Disable VPN/ad blockers that can break checkout flows
- Make sure your bank allows online/international payments

If it still fails: email support@frontendatlas.com with the time of the attempt + your account email.
