TypeScript

Typed JavaScript

FreeLibraries & build toolingtypescriptlang.org

What it is

JavaScript with static types. TypeScript 7.0, released July 2026, is a complete rewrite of the compiler in Go — roughly 10x faster type-checking and editor responsiveness than the JavaScript-based 6.0, which was the final release of the old codebase.

Why it earns a slot

Types are the guardrail that makes AI-generated code reviewable: rename a field and the compiler lists every call site instead of leaving a runtime crash. Every shadcn and Lovable scaffold is TypeScript already.

Know before you commit

The Go rewrite drops some legacy compiler APIs, so older type-checking plugins and custom transformers may need updates before you move off 6.x.

Getting started

npm install --save-dev typescript
