Angular is the next-gen framework where each tool has been designed to work with every other tool in an interconnected way. Angular JS focuses on making HTML markup dynamic and more useful to web developers, providing them a standard structure from which various components can be created quickly and easily. This blog post aims to give you a clear picture of the benefits that you can derive by using AngularJS in your projects. We have stated some key reasons that will help you understand why it’s crucial to adopt AngularJS. So let’s begin!
Most frameworks implement MVC by asking you to split your app into MVC components, and then require you to write code to string them up together again. This increases the work. Angular however, implements MVC by asking you to split your app into MVC components, but then does the rest of the work itself. Angular thus manages your components for you and also works as a pipeline to connect them.
Two Way Data Binding
AngularJS doesn’t rely on any rendering engine but uses browser parseable .html files for its partials. The HTML templates are parsed by the browser in the DOM (Document Object Model). The DOM is now the input to the AngularJS compiler. Angular then traverses the DOM template for rendering called the Directives. The input here is browser DOM and not the HTML string; this is the noticeable change between angular and all other frameworks.
Directives are one of the most powerful features of AngularJS. They are stand alone reusable elements separated from the app. All DOM manipulations are performed by Directives. They also allow you to extend HTML to answer the needs of modern web applications. Directives help you to specify how your page should be structured for the data available in a given scope.
Directives are unique, useful, powerful and reusable available only in AngularJS. With Directives you can invent new HTML syntax specific to your application.
Dependency Injection is one of the features of Angular that enables developers to develop, test and manage applications. Through dependency injection, Angular carries traditional services from server-side to web apps on the client-side. This reduces the load on the server side, making your web application lighter and faster.
AngularJS can easily handle dependencies since it allows you to divide your web app into logical modules that are dependent on each other and can be initialized separately. You thus need to work with only the module that you’re interested in. Thus Angular makes everything from application development to testing easier for developers. Dependency Injection is pervasive throughout Angular, allowing you to add a particular dependency as a parameter to AngularJS service function.
AngularJS is written entirely from the ground up to be testable. It even comes with an end-to-end and unit test runner setup.
It takes a declarative approach to make app development and testing easier by adapting and extending traditional HTML. You can declare your app’s user interface and put markup directly into HTML, making it possible to keep imperative logic separate from the presentation logic.
Flexibility with Filters
Just like directives, Filters are standalone functions that are related with the transformation of the data. They filter the data before it reaches the view and look after tasks like implementing pagination, formatting a number with decimal points, reversing a text string, and filtering an array based on conditions to list a few.
