AngularJS is a lightweight framework that can be used to create HTML-based web applications. Its declarative style allows developers to make changes in HTML code without writing it from scratch. This simplifies development and reduces costs for developers. Using AngularJS to build web applications is the way to go if you want to avoid a heavy JavaScript footprint.

AngularJS works by constructing an application that is composed of multiple directives. Each directive can be used to implement a different functionality. For example, a directive can create a read-only element. Similarly, an ng-if directive can enable or disable an HTML element based on a Boolean value.

AngularJS is also useful for building single-page applications. In addition to this, it is used to build features using declarative templates (more infomation). This framework is very easy to learn but the learning curve is similar to a hockey stick. If you want to build complex web applications, you’ll need to spend more time on understanding the framework. You can also use the Angular CLI to generate library codes and perform other tasks.

Although AngularJS has a dedicated following, it has several disadvantages. Although it allows you to create web applications in a simple way, it is slow and can degrade website performance if you build a large and complex application with it.
