## What it is
A community-maintained collection of JavaScript coding challenges for frontend interview preparation, covering handwritten implementation questions (Promise, debounce, etc.) and LeetCode-style algorithm problems. It includes reference solutions, a CLI for testing answers against test cases, and a VitePress documentation site.

## Use cases
- prepare for frontend JavaScript interview questions
- practice implementing Promise from scratch
- practice common handwritten JS questions like debounce and throttle
- solve LeetCode problems commonly asked in frontend interviews
- test my JavaScript challenge solutions against test cases
- find optimal solutions to frontend coding challenges
- study for frontend spring and autumn campus recruitment

## When to choose
- you are preparing for frontend job interviews and want a curated set of handwritten JS and algorithm questions
- you want community-reviewed reference solutions with explanations and video walkthroughs
- you want runnable test cases to verify your own implementations

## When to avoid
- you need a production JavaScript library or framework rather than study material
- you want structured courses with mentorship rather than a community question bank
- you need backend, mobile, or non-JavaScript interview preparation
