ng-if, ng-show, ng-class, and ng-style change presentation; ng-repeat and ng-switch structure lists.
Important interview questions and answers
- Q: Why does this matter?
A: ng-if, ng-show, ng-class, and ng-style change presentation; ng-repeat and ng-switch structure lists.
Self-check
- Summarize Built-in directives in one sentence.
- What would you try next in the playground?
Going deeper
In production AngularJS work, Built-in directives matters when documents, stylesheets, or apps must stay maintainable across teams and releases—not only in isolated demos.
Common pitfalls
Watch for copy-paste configs, skipping validation or tests, and mixing concerns (structure vs presentation vs behavior) in one layer.
Practice
- Apply one technique from this lesson in the playground.
- Write one interview-style sentence explaining when you would use built-in directives on a real project.
