tsc is the TypeScript compiler. It turns your .ts files into .js files that Node.js and browsers can run. Install it with npm install -g typescript. Run tsc to compile your whole project. Run tsc --watch to auto-compile on every file save. Run tsc --noEmit to check for errors without creating any files.
What is the TypeScript Compiler?
The TypeScript compiler is a tool called tsc. It reads your TypeScript files and turns them into JavaScript files.
Your browser and Node.js cannot run TypeScript directly. They only understand JavaScript. So tsc acts as the bridge between what you write and what actually runs.
Think of tsc like a spell checker for your code. It finds problems before your code ever runs. Then it produces clean JavaScript output for you.
