Why should you care?

Without a clean setup, every later lesson fights the environment.

See it live — copy this example

Run examples in an Angular CLI project (ng serve). Prefer standalone components and TypeScript strict mode.

# Install Node.js and npm
ng version
ng new angularverse --defaults
cd angularverse && ng serve

What happened?

• CLI version, new app, and serve are the bootstrap path for your Angular app.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Reproduce the snippet in an Angular CLI app.
2. Change one binding or route and re-serve.
3. Note one mistake you almost made.
4. Extract a service.
5. Add a trivial unit test later.

Remember

You can explain Install Node.js and npm simply. You ran a small Angular demo. You know one pitfall.

Install Node.js and npm in AngularVerse

Your team applies install node.js and npm on an admin UI.

Outcome: A concrete next coding step exists.
