Angular is a JavaScript framework that allows developers to build large applications using simple UI components and services. It is built on the MEAN stack, which is an acronym for four software development technologies: HTML, JavaScript, MVC, and TypeScript.
A Angular application can be built using an IDE or through a command-line interface (CLI). The CLI provides an easy interface for testing and developing applications. Angular also offers a workspace system, which allows you to host multiple projects in one environment.
Angular offers features that improve performance and simplify the development process. It also helps with unit testing and change detection. In addition, it allows for two-way data binding. This synchronization of data between view components and the model ensures that changes to DOM elements are reflected back to the model (more information).
The Angular framework uses directives, which are markers placed on DOM elements. These directives are used to modify the DOM layout, appearance, and behavior. These directives are divided into structural directives and attribute directives (more information).
Structural directives are used to modify the DOM tree. They are commonly used to modify the layout and appearance of DOM elements. Attribute directives are used to modify DOM elements based on the values of specified attributes.
Components are used to encapsulate functionality. Each component has a class that contains application data. These classes do not validate user input. They also do not log to the console. The JavaScript classes do not validate user input, but program logic can respond to user input.
