Begin by using the official TypeScript Playground – no installation needed. Write and run your first TypeScript code:

const message: string = "Hello TypeScript!";
console.log(message);

Experiment with errors, like assigning a number to a string, to see type checking in action. Optionally, install locally:

  1. Install Node.js from nodejs.org.
  2. Run npm install -D typescript@latest (current version 5.9.3).3. Create tsconfig.json with tsc --init.

Read TypeScript in 5 Minutes.

Why this step matters:
  • -Builds confidence with instant feedback on type errors
  • -Enables quick experimentation essential for hands-on learning
