Lesson 1 / 20
Getting Started
To run TypeScript, you'll want to set up the following. TypeScript is a language that adds a "type" system on top of JavaScript, developed by Microsoft. The code you write is ultimately converted (compiled) into JavaScript before it actually runs.
- Node.js: install it from the official site.
- TypeScript itself: install it by running
npm install -g typescriptin your terminal. - For a code editor, VS Code is recommended — TypeScript's type checking works out of the box.
