AngularJS Overview

AngularJS (Angular 4) is a JavaScript framework. It is a JavaScript framework that is used for building single-page web applications. IT can be easily embedded to web pages using the <script> Tag. Angular 4 used HTML, JavaScript, and TypeScript to make wonderful web applications.

AngularJS uses ng-directives to extend JavaScript in HTML WebPages. There are 3 basic directives that are most commonly used in angular 4. They are,

ng-app

This directive defines that the control is given to angular. The tag (div, p, header, etc) that has ng-app attribute has the control of the angular code.

ng-model

This directive binds value of html control tags to the application data. It initialises variables with the html input fields.

ng-bind

This directive binds the application data with the html view elements. The value of the variables are fed in the html tags that define the view.

Sample Angular 4 Code

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Angular Js</title>
    <script src="scripts/angular.min.js"></script>
</head>

<body>
    <div>
        <h2>Without Using Angular Js : Local </h2>
        <hr /> {{12+5}}
        <br>
        <br>
        <hr>
        <hr>
    </div>
    <div ng-app>
        <h2>Using Angular Js : Local </h2>
        <hr /> {{12+5}}
        <div>
</body>

</html>

Output

AngularJS example 1

Code explanation:

This is a simple Html code that you are used to and have been practicing for long so no need to explain that. So we have to similar div that have the same code one heading (H2) and one simple element {{12+5}} that is treated as plain text in html. Whereas in the second div we have define the ng-app directive that defines that the code is angular code which treats {{12+5}} as an expression which is evaluated as 17 in the angular code.

Angular as a popular development solution

Thus, aimed to ease the front-end development processes, as a simple HTML code, Angular is incredibly useful for developers to build up one-page web-applications. As a solid platform for web-applications development, Angular is highly helpful for programmers, as it allows them to unfold the development tasks that are regularly challenging the field professionals.

Even more, Angular provides the application to be used both for smartphones and the web, so it is mobile and web-friendly. For the coders the process of transferring a code written in JavaScript (a top programming language) into a dynamic content with Angular is uncomplicated and understandable.

According to the info given by Statista, in 2020, Angular is one of the most used solutions frameworks among web software programmers. It is being used by a wide range of top industry giants as well. It all creates a network community of the Angular developers, which makes it quite wide and sufficient. These all can provide enough information exchange and professional expertise to keep improvement processes within the technology through the community. 

Besides, it gives the programmers an opportunity to follow a well-paid career path and engage themselves in the web-application development job market. You can also get acquainted with the current market trends research of Angular developer salary range provided by Devox Software.

In addition to that, Angular development is easy to test, has no redundant coding, is faster to use, has a simple architecture based on the MVC framework. Worth noticing that Google regularly updates it.

To sum up, Angular, as a single page development solution, has a solid, proven background to be popular in its field. It has a community of programmers and organizations that apply it in their web development processes very widely. It is also adaptable to the needs, continually improving, is friendly to use by programmers, is uncomplicated and straightforward, but highly efficient for its industry.
