Explanation

AngularJS, the JavaScript framework developed by Google, uses various directives to extend HTML and provide additional functionality. Here are some commonly used AngularJS directives: ng-app: Declares the root element of the AngularJS application and initializes the AngularJS framework. ng-controller: Defines the controller for a particular section of the HTML. It establishes a scope for the controller, allowing it to interact with the view. ng-model: Binds an HTML input element to a property on the controller's scope, enabling two-way data binding. ng-bind: Similar to ng-model, it binds an HTML element's content to an expression in the controller's scope. ng-repeat: Iterates over a collection (such as an array or object) and duplicates a section of HTML for each item in the collection. ng-if and ng-show/ng-hide: Conditionally show or hide elements based on a given expression. ng-click, ng-change: Listens for click or change events and executes a specified expression. ng-submit: Listens for the form submission event and executes a specified expression. ng-class and ng-style: Dynamically apply CSS classes or styles based on expressions. ng-include: Includes an external HTML file into the current template.
