This lesson

An orientation to the AngularJS track—how the playground works, vocabulary, and what you will build next.

Migration literacy prevents rewriting working legacy apps from scratch.

You will apply Migration overview 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.

After solid JavaScript—and ideally TypeScript—before starting the angularjs track.

Strangler patterns, hybrid apps, and official upgrade paths move teams toward Angular or other stacks.

Important interview questions and answers

  1. Q: Why does this matter?
    A: Strangler patterns, hybrid apps, and official upgrade paths move teams toward Angular or other stacks.

Self-check

  1. Summarize Migration overview in one sentence.
  2. What would you try next in the playground?

Going deeper

In production AngularJS work, Migration overview 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 migration overview on a real project.

Interview prep

Safe migration strategy?

Inventory modules, extract services, strangler-route features to Angular/React/Vue, keep tests on critical paths.
