A module is a container for the different parts of the application like a controller, services, filters, directives, etc. It is treated as a main() method. All the dependencies of applications are generally defined in modules only. A module is created using an angular object’s module() method. For example:

var app = angular.module(‘myApp’, []);

In AngularJS, a module is a container for different parts of an application, such as controllers, services, directives, filters, and more. It is a way to organize and structure the components of an application into cohesive units. Modules help in managing the dependencies between different parts of the application and provide a way to group related functionality together.

To define a module in AngularJS, you use the angular.module function. Here’s a basic example:

javascript

// Define a module named ‘myApp’
var myApp = angular.module(‘myApp’, []);// Define a controller within the ‘myApp’ module
myApp.controller(‘myController’, function($scope) {
// Controller logic goes here
});

In this example, myApp is the module, and it can depend on other modules by passing them as dependencies in the second parameter of the angular.module function. The controllers, services, directives, etc., can then be defined within this module.

Modules play a crucial role in AngularJS applications by promoting modularity, reusability, and maintainability
