This lesson

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

You need a clear map of the AngularJS track so hooks, state, and tooling do not feel like magic.

You will apply Custom directives intro 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. Also read the interview prep blocks.

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

Directives return link functions or compile templates to create reusable DOM behavior.

Important interview questions and answers

A: Directives return link functions or compile templates to create reusable DOM behavior.

Self-check

Summarize Custom directives intro in one sentence.
What would you try next in the playground?

Going deeper

In production AngularJS work, Custom directives intro 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 directives intro on a real project.

Playground

Runs in your browser in a sandboxed frame. Backend runners appear when this track’s profile allows them.
