AngularJS - Overview

Understand AngularJS as a JavaScript framework built around templates, scopes, directives, dependency injection, and a digest cycle.

How it works

AngularJS extends HTML with directives and connects templates to JavaScript models through scopes and data binding. Modules group application components, while dependency injection supplies services. The digest cycle propagates changes to bindings. Keep responsibilities small and avoid direct DOM manipulation when a directive or binding fits.

Practice checklist

• Use examples that match the AngularJS version in the existing application.
• Keep user input, asynchronous states, and failures visible and understandable.
• Test keyboard access and validate important rules on the server.
• Review dependency support and migration needs before production changes.
