async pipe subscribes and unsubscribes automatically—reduces memory leaks.
Important interview questions and answers
- Q: Why does this matter?
A: async pipe subscribes and unsubscribes automatically—reduces memory leaks.
Self-check
- Summarize Async pipe in one sentence.
- What would you try next in the playground?
Going deeper
In production Angular work, Async pipe 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 async pipe on a real project.
