Install TypeScript
You can grab the compiler globally or as a project dependency.
bash
# Globally
npm install -g typescript
# Project-local (recommended)
npm install --save-dev typescriptAfter installing, run npx tsc --init to scaffold a tsconfig.json. TypeScript 5.9+ produces a streamlined, prescriptive config out of the box.
