Angular comes in a variety of forms ( previously angular.js)
When angular.js was first released in 2010, it was known as angular.js.

AngularJS is an open-source front-end framework that is built on javascript and is mostly used to create single-page web apps. It improves static HTML by making it dynamic. It provides directives to extend existing HTML.

Angular is a major version upgrade to AngularJS and an alternative to it. From version 2.0 onwards, Angular will be released. Compared to AngularJS, it is really quick. It is simple to develop and has the command line interface tool Angular CLI.

Angular and AngularJS are well-known frameworks for building web apps among most front-end developers. However, after you begin learning Angular, you may find that you understand a lot of things because some fundamentals are the same.

Comparison between Angular and Angular JS

  • Languages

AngularJS code is written in javascript.

Angular code is written in typescript.

  • Using Directives

While both Angular and AngularJS make use of directives, how they are used differs.

AngularJS has a set of directives, whereas Angular has a set of standard directives. When using the Directives, one must use caution. When creating a two-way binding with AngularJS, for example, you’ll need to employ the ng-model. ng-bind is used for one-way binding.

Only the ngModel is available in Angular. One-way binding is represented by the symbols “[],” and two-way binding is represented by the symbols “[()].” Property binding is done using “[],” while event binding is done with “().”

  • Components

Their Components differ, as can be seen. Angular leverages TypeScript, which is a superset of ES6 with backward compatibility with ES5.

Angular JS, which is built on JavaScript, employs words like scope and controllers, whereas Angular employs a component structure. AngularJS employs directives, whereas Angular is component-based.

  • Routing

In Angular JS @routeProvider when, then are used to provide routing information.

In angular, @Route configuration is used to define routing information.

  • Architecture

AngularJS — The key component of this framework is the model-view-controller (MVC), which maintains data, logic, rules, and specifies how the applications operate.

The model is where all data management is kept.

After examining the information in the model, the view generates the output.

The input is received by the controller, which turns it into commands that are sent to the model and view.

Angular — It uses directives with templates as components. In Angular, there are two types of directives.

Structural directives replace elements in the DOM to change its layout.

Attributive directives modify how the DOM behaves and how the element appears.

  • Mobile

AngularJS does not support mobile devices, whereas Angular does.

  • Tool Support

The framework requires on third-party tools like IDE and WebStorm to support Angular JS.

Angular employs the Command Line Interface (CLI) to speed up application development.

  • Dependency Injection

In Angular JS ,DI is not used.

Hiearchical DI system is used in Angular.

  • Management

AngularJS project is difficult to manage with increasing size of the source code.

Angular code is better structured, is easy to create and manage bigger applications.

These are the main differences between Angulr and Angular JS.
