Before you start
The everyday toolkit: code editors, terminal basics, package managers, and browser DevTools.
Professional developers spend as much time in tooling as in language syntax—weak tooling slows every fix.
Every role that writes or ships software: front-end, back-end, data, and DevOps-adjacent work.
Foundations lessons plus MCQs per slug; apply each idea immediately in your local editor and terminal.
Early in your journey—ideally before or alongside Git and your first language track.
