Eleven courses, three ways to pay
Everything we teach, in one place. Free courses first — they're the same quality as the paid ones, just shorter.
Free courses
5 coursesComplete courses at no cost. No account, no card, no trial that expires.
Branch, merge and rebase without the cold sweat. The ten commands that cover ninety percent of real work.
The language itself — values, functions, async — explained once, properly, with nothing to install.
Stop fighting the browser. Two layout systems, a handful of rules, and layouts that hold up on any screen.
Move, find, pipe and script. An hour that pays itself back every single week.
A method, not a trick: read the error, form a hypothesis, bisect, fix, and leave a test behind.
One-time payment
5 coursesBuy once and keep it, updates included. Prices include VAT.
Build a complete product with React — state, forms, data fetching, routing — and understand every decision.
From annotations to generics and inference — types that document your code instead of arguing with you.
Design, build and ship an API you would trust in production — auth, validation, migrations and logs included.
End-to-end tests that catch real breakage and almost never flake. Fast enough to keep in every pull request.
Caches, queues, databases and trade-offs — the vocabulary senior work and interviews both assume.
