AngularJS - Scopes

Understand scope inheritance, binding, lifecycle, and controller boundaries.

How it works

Scopes connect controllers and templates and form a hierarchy. Understand prototypal inheritance, isolate scopes in directives, and use explicit component bindings when practical. Clean up long-lived listeners when their scope is destroyed.

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.
