AngularJS is a framework that extends HTML and provides directives for dynamic templates. The framework also allows developers to craft reusable components and create their own custom directives. Directives are basically objects that describe the behavior to be applied to DOM elements. They also abstract DOM manipulation logic. For example, a directive can be used to transform an element into a new one.

Angular is a flexible framework that allows developers to build features quickly. It’s supported by nearly every editor and IDE, enabling developers to concentrate on building apps instead of worrying about the underlying code. This helps to increase app performance by eliminating code work and enabling developers to focus on building the app’s features.

Angular also has the benefit of being cross-platform. It is compatible with Windows, macOS, and Linux, and can be used to create native mobile apps. Its intelligent API allows for complex choreographies and high-performance animation. Its lightweight nature makes it ideal for mobile apps, as well as desktop applications.

Angular uses TypeScript as its primary programming language. Its latest version, Angular2, was released in September 2016. This is a complete rewrite of the framework, designed to meet modern web needs. Because of the different syntax, developers had to make numerous changes to migrate from AngularJS to Angular. Fortunately, the Angular team was able to come up with migration tools. Using the Angular CLI, developers can easily create Angular projects. Then, they can create components, services, and guards. The CLI is available as a NodeJS module.
