effect() runs side effects when signal dependencies change—use carefully in components.
Important interview questions and answers
- Q: Why does this matter?
A: effect() runs side effects when signal dependencies change—use carefully in components.
Self-check
- Summarize Effect basics in one sentence.
- What would you try next in the playground?
Going deeper
In production Angular work, Effect basics 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 effect basics on a real project.
