Angular Intro
Angular helps you build scalable single-page applications with TypeScript.
What is Angular?
Angular is a full-featured front-end framework for building web applications.
- Built with TypeScript
- Uses components and templates
- Includes routing, forms, HTTP, and dependency injection
- Supports standalone APIs (no NgModules needed)
- Works great for single-page applications (SPAs)
How Angular Works
Angular compiles your templates into efficient JavaScript and updates the DOM when your component state changes.
- Declare UI with HTML-based templates
- Bind data with interpolation and directives
- Handle events and user input
- Fetch data with the HttpClient (Observables)
- Navigate with the Router

})
export class App {}
bootstrapApplication(App);
<app-root></app-root>
