AngularJS is a framework created by Google.It has an established market position and huge community support. It was one of the first frameworks to introduce the application development trend in the single page application approach. This approach allows you to create applications with which the user interacts in real time, without waiting for subpages to load and the "white page" effect. Interaction with this type of application is engaging and fluid.
AngularJS bases its operation on the MVC architectural design pattern
It assumes the division of the application into three layers, each communicating with one another: model, view and controller. These layers separate business logic from its presentation. Designs created this way are scalable and easy to maintain.
Angular JS is AsynchronousIn SPA applications, communication with the server takes place via asynchronous requests that do not block the main thread of the application. In the event of time-consuming operations on the server, the application does not have to stop. It is available all the time while data is loading in the background.
ModularityAngularJS has a modular structure enabling work on applications even in large teams. This contributes to the rapid implementation of set goals in all types of applications, from small to very large.
Angular JS is component-based framework
One of the main principles of systems written using the AngularJS framework are components - specialized blocks responsible for specific system functions, which can be used in many places of the application. Adding new modules consisting of frequently repeating elements such as modal windows, text boxes and buttons is no longer a problem; on the contrary, it is quick and pleasant. The component approach also allows for easy and rapid modification of the appearance or the way many system components work simultaneously. Changes made to the source code of the component are propagated to all its instances.
ReactivityAngularJS significantly facilitates the manipulation of data that is presented to the end user in real time, without the need to reload the page. All thanks to the digest loop mechanism. It checks if the current state of the variables presented in the view has changed and whether it is necessary to refresh the remaining data dependent on this variable. This approach allows developers to focus fully on the implementation of assumptions, instead of taking care of the correct state of data in various corners of the system.
