In AngularJS, you typically don't use the require keyword as you would in CommonJS or Node.js. AngularJS uses dependency injection to manage dependencies between different components of the application, and you don't directly use require to load modules like in a Node.js environment.

Instead, you use AngularJS's dependency injection system to inject components, services, and other dependencies into your application. The most common places you use dependency injection in AngularJS are:

  1. Controller: You can inject services, factories, or other components into your controllers using the controller's constructor function.

    Example:

    javascript
    angular.module('myApp').controller('MyController', ['$scope', 'myService', function($scope, myService) { // Controller logic here }]);
  2. Service or Factory: Services and factories are typically singletons that provide data or functionality throughout the application. You can inject other services or components into a service or factory using its constructor function.

    Example:

    javascript
    angular.module('myApp').factory('myFactory', ['someService', function(someService) { // Factory logic here }]);
  3. Directive: Directives can also have dependencies that can be injected using the directive's link function or controller function.

    Example:

    javascript
    angular.module('myApp').directive('myDirective', ['myService', function(myService) { // Directive logic here }]);

AngularJS automatically resolves the dependencies and injects the correct components when they are needed. You specify the dependencies using an array of strings containing the names of the components you want to inject, followed by the function that uses those dependencies.

Remember that AngularJS is an older framework, and in modern Angular (Angular 2+), you use a different module system and dependency injection mechanism. If you are starting a new project, consider using the latest version of Angular (Angular 12 at the time of writing) for a more modern and supported development experience.
