How the build track works
Learn by finishing something
Most tutorials end where the interesting part begins. The build track is the other way round: you pick a project you actually want to exist, and the work of getting there is broken into 140 small exercise stops across 20 projects. Each stop is one idea — a loop, a function, a fetch — with a task you complete in the browser before the next one unlocks.
Nothing to install
Everything runs in the page. No toolchain, no environment to get wrong before you have written a line — which is where most people quit.
Your language
The same projects are laid out for several languages, so you can follow the one you are learning rather than translating someone else's choice as you go.
Checked as you go
Each stop is verified against real cases, so “it looked right” and “it works” stay honest about the difference.
You can browse every project and its stops below without an account. Signing in is what lets your progress carry over between sessions, and what puts the people also working through them within reach.
