AngularJS and Angular Directives

Angular is a front-end development framework that enables building applications quickly and easily. Using a template language, it extends HTML and supports an extensive collection of existing components. Its support for nearly every IDE and editor enables you to focus on building the application rather than coding. This helps you build more effective apps in less time by eliminating a lot of code work.

Angular is an excellent choice for developers who need a robust framework to build cross-platform mobile applications. Compared to AngularJS, Angular is easier to learn and use in smaller applications. It is also better for developers who plan to build scalable applications. It also provides more centralized management of larger applications.

Angular uses directives to define the behavior of DOM elements. Each directive is associated with a particular controller and is injected into the HTML. Angular applications consist of a tree of Angular components. Each component is composed of a controller and a view. The controllers and views work together to produce the final HTML that is viewed by the user.

You can use ng-bind to set the text of a DOM element to an expression. For example, you can use ng-bind to display the value of a collection item. Changes made in application scope reflect instantly in DOM. You can also use ng-bind to define a JavaScript controller class that evaluates HTML expressions. Using ng-bind, you can also use a basic if statement directive to instantiate a following element if certain conditions are met. The if statement directive is called once when the compiled element is initialized.
