Our mission
A clear path from "never coded" to "ships features".
The web is built on JavaScript. But for too many beginners, the on-ramp is a maze of paywalled bootcamps, outdated tutorials, or YouTube playlists abandoned halfway through.
We're building a single, free, no-friction place where anyone can learn JS — and the languages and frameworks built on top of it — in their browser, from zero, without a credit card.
Principles
Three rules we won't break.
🆓
Free, always.
No paywall, no signup wall. The core lessons, references, and examples are free forever — funded by ads & optional pro features, never gated behind them.
🎯
Beginner-first.
Short paragraphs. Real examples. Capability-style titles. We optimize for the absolute beginner — if they get it, advanced devs definitely will.
🚀
Modern by default.
No var, no IE-era patterns, no jQuery muscle memory. ES2024+ syntax, modules, async/await, and the platform APIs that ship today.

The story
Where we are. Where we're going.

Under the hood
Built with the tools we teach.
jsschools.com is a static site, generated with Astro, written in TypeScript, served from the edge. It loads fast because we send tiny amounts of JavaScript — and zero unused frameworks.
