Important interview questions and answers
- Q: Why does this matter?
A: Custom filters format template output—prefer one-way binding over filters for heavy logic.
Self-check
- Summarize Custom filters in one sentence.
- What would you try next in the playground?
Going deeper
In production AngularJS work, Custom filters 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 custom filters on a real project.
