This lesson

This lesson teaches Maintenance checklist: the concepts, APIs, and habits you need before advancing in AngularJS.

Lists without stable keys break focus, animation, and state in production tables and feeds.

You will apply Maintenance checklist in contexts like: Long-lived intranet apps, government portals, and codebases not yet moved to Angular, React, or Vue.

Write JavaScript for AngularJS 1.8, click Run—register modules/controllers, then mountApp(moduleName, templateHtml) in #ng-app; printOutput feeds the terminal.

When hooks, state, and effects from intermediate lessons are familiar.

Audit watchers, document module boundaries, add tests around critical flows before refactors.

Important interview questions and answers

  1. Q: Why does this matter?
    A: Audit watchers, document module boundaries, add tests around critical flows before refactors.

Self-check

  1. Summarize Maintenance checklist in one sentence.
  2. What would you try next in the playground?

Going deeper

In production AngularJS work, Maintenance checklist 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

  1. Apply one technique from this lesson in the playground.
  2. Write one interview-style sentence explaining when you would use maintenance checklist on a real project.
