To install AngularJS, you can follow these steps:

  1. Download AngularJS: Visit the official AngularJS website (https://angularjs.org/) and download the latest stable version of AngularJS. You can either download the compressed file (.zip) or use a package manager like npm or Bower.

  2. Include AngularJS in your project:

    • If you downloaded the compressed file, extract it and include the angular.js file in your project directory.
    • If you're using npm, you can install AngularJS using the command:
      npm install angular
    • If you're using Bower, you can install AngularJS using the command:
      bower install angular

  3. Add AngularJS to your HTML file: Include the AngularJS script tag in your HTML file within the <head> section:

    html
    <script src="path/to/angular.js"></script>

  4. Set up your AngularJS application: You need to define an AngularJS module and bootstrap it to your HTML document. For example:

    html
    <html>
<head>
    <title>My AngularJS App</title>
    <script src="path/to/angular.js"></script>
</head>
<body ng-app="myApp">
    <div ng-controller="myCtrl">
        {{ greeting }}
    </div>

    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope) {
            $scope.greeting = 'Hello, AngularJS!';
        });
    </script>
</body>
</html>

  5. Verify installation: Once you have included AngularJS in your project and set up your AngularJS application, you can open your HTML file in a web browser. If everything is set up correctly, you should see "Hello, AngularJS!" displayed in the browser.

These are the basic steps to install AngularJS and create a simple AngularJS application. Depending on your project requirements, you may need to include additional libraries or use a build tool like Webpack or Angular CLI for more complex applications.
