AngularJS - Expressions

Display and evaluate simple expressions in AngularJS templates.

How it works

Expressions read values and perform simple operations in templates. Keep them side-effect free and concise; place nontrivial logic in a controller or service. Remember that templates can expose data, so avoid binding secrets or untrusted HTML.

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.
