How the challenges work
Interactive coding challenges that run JavaScript directly in your browser — write code, run it, see the output immediately, and earn XP as you clear challenges.
- No local setup — the code editor and runner are both in the browser.
- Immediate feedback on whether your code produces the right output, rather than a wait for review.
- XP and levels give a visible sense of progress across a series of challenges rather than one-off exercises.
- Sits between a coding-basics course and a full project — short enough to fit in a spare 15 minutes, but harder than a copy-along tutorial since you have to produce the working code yourself.
Cost and access
