What is angular?

Angular is an open source framework developed by Google to facilitate the creation and programming of single-page web applications.

Angular is one of the most powerful and popular JavaScript development frameworks today.

It is an MVC (Model View Controller) framework, developed by Google that facilitates the creation and programming of single-page web applications, SPA (Single Page Application) websites.

We can also say that Angular is a development platform, built on TypeScript, that allows you to create scalable web applications.

Before talking about what Angular is and all its functionalities, we must be clear about what a framework is; It is a conceptual and technological support structure defined with specific software artifacts or modules. That is, a kind of scheme or template based on technology that allows you to work in a much simpler way and thus avoid programming errors.

Angular is a collection of libraries with many features such as form management, client-server communication, routing etc. It allows you to develop, test, compile and update the source code of an application.

It also makes it possible to tackle projects from a single developer to enterprise-level applications. It is easy to update and takes advantage of developments with little effort.

Angular's main programming language is Typescript. This code is complicated with JavaScript and can be executed without problems on any platform. It is not mandatory to develop an Angular application but it is recommended. It makes the code base easier to understand and maintain.

Angular uses DOM (Document Object Model) which treats an XML or HTML document as a tree structure in which each node represents a part of the document.

It also uses two-way binding, where the model state reflects changes made to the corresponding UI elements. For its part, the state of the user interface reflects any change in the state of the model.

Additionally, Angular uses the Jasmine testing framework that offers multiple functionalities for writing different types of test cases.

Angular templates store the user interface (front-end) and business logic (back-end) code separately .

In addition, the main editors and integrated development environments (IDEs) already offer extensions to be able to work with this framework more comfortably.

Angular has a command line wizard to create base projects and also integrates well with testing tools and Ionic, which makes it easier to create responsive web.

An Angular application has a root module, called AppModule, which provides the bootstrapping mechanism for the application. It has pieces of code that contain data and application logic and a component that defines part of the user interface.

Angular also uses templates that are a combination of Angular markup with HTML to modify HTML elements before they are displayed.

For its part, metadata tells Angular how to process a class. The services allow you to share information between components or make requests to APIs to obtain the information. Angular directives extend the HTML and give it new syntax. They can be easily detected because they have the ng prefix.
