angular.js advantages and features

Advantages of Angular.Js

In order to understand the purpose and value of Angular, you must first understand something about javascript.

JavaScript is a programming language that was written in 2 weeks and was hated by developers for years because it was slow, difficult to work with, and frustrating to debug.

But in recent years, tooling around javascript has improved significantly and companies like google, apple, and Microsoft have put millions of dollars into making javascript fast.

This has made it not only possible, but even enjoyable to write large applications to run in the browser.

About Angular:

A framework for writing manageable, clean, full-featured applications in the browser with javascript. Angular was originally written by Misko Hevery. His intention was to create a way for designers to be able to do HTML design using components with actual functionality.

As he got further and further along in the project, it became obvious that the framework he was building was actually a great way for developers to build entire sites. As a result, Angular was born.

Angular Benefits and Features:

  • These range from straightforward features of testability and two-way binding, to more vague concepts such as cohesion and guidance.
  • Each of the benefits and features will provide a compelling case by themselves as to the value of Angular, but overall, there is one reason why Angular is a great framework to use for your development, and that is a reduction of cost due to reduction of time spent by developers and other staff.
  • Regardless of whether we are speaking of the learning curve, staff recruiting and retention, the development time of a project, or the maintenance costs of a project, using Angular reduces the time and therefore, costs of building web applications, and that is usually the primary reason to choose a technology.

Testability:

  • Angular was designed with testing in mind right from the start.
  • Angular makes testing any of its components very easy through both unit testing and an end to end, or functional testing.
  • Its unit testing is facilitated by a built-in mocking component called ngMock that will let you isolate Angular from your back-end server.
  • End-to-end testing is facilitated by a tool created by the angular team called protractor.
  • A tool called karma, which was also developed by the Angular team makes it easy to run your tests in multiple browsers all at the same time, and it has become extremely popular for automating testing, even on projects which don’t use Angular
