What is Angular and Benefits of Using Angular....


What is Angular?
Angular is basically is an open-source, JavaScript-based client-side framework that helps us to develop a web-based application. Actually, Angular is one of the best frameworks for developing any Single Page Application or SPA Applications. The definition of Angular according to the official documentation of Angular in the angular.io web site –
“Angular is a structural framework for dynamic web applications. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application components clearly and succinctly. Its data binding and dependency injection eliminate much of the code you currently have to write. And it all happens within the browser, making it an ideal partner with any server technology.” – (courtesy – Angular Conference, 2014).
So, in a very simple word, Angular is -
  • An MVC based structure framework
  • A Framework for developing SPA (Single Page Application) based application
  • Support client-side templating features.
  • Provides us a facility to perform unit test so that our code can be tested before deployment. 

Benefits of Using Angular

Angular is a client-side based on an open-source framework maintained by Google. The library is capable of very first reading the HTML page, which provides additional custom tag attributes embedded into it. Those attributes are interpreted as directives that instruct Angular Framework to bind input or output parts of the page to a model that is represented by standard JavaScript variables. The values of those JavaScript variables can be manually set within the code or retrieved from static or dynamic JSON resources including any server-side data provider like REST API or others.
The main benefits of using Angular in web applications are:- 
  • Angular modifies the page DOM directly instead of adding inner HTML code which is faster.
  • Data binding does not occur on each control or value change (no change listeners) but at particular points of the JavaScript code execution. That dramatically improves performance, as a single bulk Model/View update replaces hundreds of cascading data change events.
  • There is no need to use observable functions. Angular analyzes the page DOM and builds the bindings based on the Angular-specific element attributes. That requires less writing, meaning the code is cleaner, easier to understand, and has fewer errors.
  • Extended features such as dependency injection, routing, animations, view encapsulation, and more are available.
  • It is supported by IntelliJ IDEA and Visual Studio .NET IDEs.
  • It is supported by Google and a great development community.
  • Angular is a comprehensive solution for rapid front-end development. It does not need any other plugins or frameworks.
  • Angular is unit testing ready, and that is one of its most compelling advantages.

Angular Architecture

Angular Architecture is divided into different parts like Component, Template, Directive, Service, and Module. Before you start to develop your application, you should have knowledge about the purpose of each part of the application. So that you can make your application smoother and faster. Below is the figure of angular architecture. Angular Architecture In this chapter, we will see each term in detail. Module Angular Applications are modular and Angular has its own modularity system called NgModule. Every Angular application has at least one class with a @NgModule decorator, it is the root module, conventionally named as AppModule. To use any component into an application you need to declare it into the related module. Angular Module is class with a @NgModule decorator. Code Snippet of Angular Module The most important properties of @NgModule are : declarations:  declaration property contains a li

Benefits of Learning Angular

Benefits of Learning Angular There’s a lot of platforms and tools out there, so what makes Angular so special? What sort of advantages does it bring to the table, that it’s so important for developers to know its ins and outs? Here are some of Angular’s most impressive advantages: Less Coding The best code is short but effective, getting the most functionality with expending the least effort. Fortunately, Angular supports Model View Controlling architecture (MVC). All the developer needs to do is split their code to fit into the MVC architecture, and Angular takes care of the rest! No worries about having to do the MVC pipeline. Ease of Integration There’s a host of frameworks out there that have Angular already built into them, including Kendo UI, Wijmo, and Ionic, to name a few. That just goes to show that Angular plays well with others. Single Page Applications Supported A Single Page Applications is defined as a web application that loads a single HTML page. The page
