Reasons for learning the advanced concepts of AngularJS

What is AngularJS?

AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly.

Angular3S’s data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology.

Lets see benefits and reasons for learning the advanced concepts of AngularJS:

Visual Studio Ide with intelligence

The best editor for writing Typescript code for Angular is Visual Studio. One can work on a community version of Visual Studio, which is free. If one writes code into Visual Studio, it has great features like intellisense, through which one does not need to write full code. This makes the coding faster and saves time and effort.

It is Object Oriented with Typescript.

Typescript is the main language which is used for writing Angular2. Typescript is a superscript of JavaScript, which is an optional statically typed language. Typescript uses object-oriented features. A class can contain properties and methods that can be called into view when needed.

Data models are POJO.

This is also one of the important features of Angular. Its data model is in plain old Javascript objects. The advantage is that one does not need to integrate into an existing data source. That makes the code clean because there is no need to write boilerplate code, which helps in maintaining the code easily.

MVC Architecture

AngularJS follows the popular MVC pattern. MVC is the term that is used to divide the code login into Model View and Controller systems. Angular2 does away with the concept of a controller in favour of components. Angular does not follow the traditional MVC pattern, but it follows the MVVM (Model-View-ViewModel) design pattern.

Maintained and Developed by Google and Powered by Microsoft

Angular is developed and maintained by internet giant Google. Unlike other frameworks, which are either developed by a community or an individual, this framework is the brainchild of a Google developer. So, if any developer learns it, he’s sure that it’s going to stay for a long time. The prime language for developing Angular2 applications is Typescript, which is developed and maintained by Microsoft.

Two-Way Data Binding Reduces a Ton of Boileplate

Two-way data binding is a unique feature of AngularJS through which if data is inserted in one place of the model (HTML, input, like text box and text area), it gets changed instantly in the other and vice-versa. In a traditional MVC model, the developer has to manually write code into models to operate data and show it into view, which generates a lot of boilerplate code. On the other hand, Angular’s two-way data binding functionality binds models to HTML elements, which saves developers from writing any unnecessary code.

Excellent Pipe Operators or Filters

Angular comes with a great feature called Angular Pipes. Using the Pipe filter, the developer can control the data display directly in the HTML view. There are a bunch of Angular JS filters which prove to be very handy for developers to format the data and display it. Data filters can also be applied to services, models, and view templates. Not only that, but developers can also write their own custom filters and use them in the application.

Component and Module-Based

An Angular 2 module is a block of code that is created for a specific purpose. And any individual module exports value, function, a class which other modules can import and make use of. In fact, the angular framework itself is the collection of libraries and modules. Also, the component is one of the essential parts of Angular2. Using components, one can make the code which is reusable. A component is mainly a Javascript class with some metadata attached to it.

Directive Define Behavior

In the traditional way, the views extend the DOM to display data and manipulate the DOM to embed behaviour. In short, the behaviour code is explicitly written. On the contrary, the manipulation code of the DOM in Angular is written in ng directives rather than in the view. That way, angular treats the view as normal HTML code, which acts as the holder of the data, and that’s the reason it gets integrated into HTML beautifully.
