Angular is a framework for building client applications in HTML and either JavaScript or a language like TypeScript that compiles to JavaScript.

The framework consists of several libraries, some of them core and some optional.

You write Angular applications by composing HTML ##BAD TAG##texthelpns>templates with Angularized markup, writing ##BAD TAG##texthelpns>component classes to manage those templates, adding application logic in ##BAD TAG##texthelpns>services, and boxing components and services in ##BAD TAG##texthelpns>modules.##BAD TAG##texthelpns>

Then you launch the app by ##BAD TAG##texthelpns>bootstrapping the ##BAD TAG##texthelpns>root module.##BAD TAG##texthelpns> Angular takes over, presenting your application content in a browser and responding to user interactions according to the instructions you've provided.##BAD TAG##texthelpns>
