In this article, we will learn about Angular JS & Angular, along with understanding the significant distinction between them.
Angular JS: AngularJS is a JavaScript open-source front-end framework that is mainly used to develop single-page web applications(SPAs). It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML. Its features like dynamic binding and dependency injection eliminate the need for code that we have to write otherwise. AngularJS is rapidly growing and because of this reason, we have different versions of AngularJS with the latest stable being 1.7.7. It is also important to note that Angular is different from AngularJS. It is an open-source project which can be freely used and changed by anyone. It extends HTML attributes with Directives, and data is bound with HTML.
Example: This example describes the String interpolation in AngularJS.
HTML
<!DOCTYPE html>
<html>
<head>
<script src=
</script>
</head>
<body>
<h1 style="color:green">

</h1>
<h3>

<div ng-app=""
ng-init="Course='AngularJS';

Output:
Angular: It is a popular open-source Typescript framework created by Google for developing web applications. Front-end developers use frameworks like Angular or React for presenting and manipulating data efficiently. Updated Angular is much more efficient compared to the older version of Angular, especially, since the core functionality was moved to different modules. That’s why it becomes so much fast and smooth compare to the older one. Newly added angular CLI, & with the help of this command-line interface, we can install the required packages that facilitate creation & make the complex-structured code into a modular form that can be easy to manage.
Example: This example describes the String interpolation in Angular.
app.component.html
<h1
[style.color]="'green'"
[style.font-family]="'Arial'"
[style.text-align]="'center'">
{{ title }} : {{ about }}
</h1>
<p [style.font-weight]="'bolder'">
This example illustrates {{ data }} in Angular.
</p>

app.component.ts
import { Component } from "@angular/core";
@Component({
selector: "my-app",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.css"],
})
export class AppComponent {
title = "GeeksforGeeks";
about = "Learning Portal for Geeks";
data = "String Interpolation";
}

Output:
Difference between the AngularJS & Angular: Although, there are significant key differences between Angular JS & Angular, which can be categorized in the following way:
Category | Angular JS | Angular |
|---|
Architecture | It supports the Model-View-Controller design. The view processes the information available in the model to generate the output. | It uses components and directives. Components are the directives with a template. |
Written Language | Written in JavaScript. | Written in Microsoft’s TypeScript language, which is a superset of ECMAScript 6 (ES6). |
Mobile support | It does not support mobile browsers. | Angular is supported by all the popular mobile browsers. |
Expression Syntax | ng-bind is used to bind data from view to model and vice versa. | Properties enclosed in “()” and “[]” are used to bind data between view and model. |
Dependency Injection | It does not use Dependency Injection. | Angular is supported by all the popular mobile browsers. |
Supported Languages | It only supports JavaScript. | It provides support for TypeScript and JavaScript. |
Routing | AngularJS uses $routeprovider.when() for routing configuration. | Angular uses @Route Config{(…)} for routing configuration. |
Structure | It is less manageable in comparison to Angular. | It has a better structure compared to AngularJS, easier to create and maintain for large applications but behind AngularJS in the case of small applications. |
CLI | It does not come with a CLI tool. | It comes with the Angular CLI tool. |
Examples Application | iStock, Netflix, and Angular JS official website. | Upwork, Gmail, and Wikiwand. |
Note: Angular is a great framework, it has many improvements in terms of AngularJS, it is good for bigger applications along with good for smaller applications, but there is a huge competition between Angular and AngularJS.
