This lesson

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

Without ngModule basics, you will struggle to read or extend AngularJS codebases and playground exercises.

You will apply ngModule basics 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 you can explain the previous lesson's ideas without copying starter code.

angular.module(name, deps) registers controllers, services, directives, and config blocks for one app boundary.

Tip: Retrieve an existing module with angular.module('name') (no second arg)—passing [] twice throws “module already exists”.
