Understanding the Difference Between Angular and AngularJS
What Is The Difference Between Angular And Angularjs
AngularJS refers to the first version of the Angular framework, which was released in 2010 by Google. It is often called AngularJS to differentiate it from the later versions, which are referred to simply as Angular. While AngularJS uses JavaScript, Angular uses TypeScript, a superset of JavaScript that offers additional features like strong typing. Angular has a more modular and efficient architecture, improved performance, and better support for mobile development. Additionally, Angular comes with features like Ahead-of-Time compilation and a more streamlined syntax. Overall, Angular is considered the more modern and advanced version of the Angular framework.

1 - Angular:
Angular is a modern and powerful TypeScript based open source front end web application framework developed and maintained by Google.
Angular is also referred to as Angular 2+ or simply Angular, as it represents a complete rewrite of the original AngularJS framework.
2) AngularJS:
AngularJS is a JavaScript based open source front end web application framework developed by Google.
AngularJS is the original version of the framework, and it is now considered outdated compared to Angular.
3) Architecture:
Angular follows a component based architecture where an application is built using components, services, modules, and other features. It uses TypeScript for creating components, services, and modules.
AngularJS uses a controller based architecture where controllers are used for handling the logic of the application.
4) Performance:
Angular is more performance oriented and provides better performance optimizations compared to AngularJS. It uses faster change detection mechanisms and improved rendering techniques.
AngularJS may face performance issues with larger and complex applications due to its two way data binding mechanism and digest cycle.
5) Language:
Angular is written in TypeScript, which is a superset of JavaScript that provides static typing and other advanced features.
AngularJS is written in JavaScript and does not support TypeScript natively.
6) Dependency Injection:
Angular has a more advanced and improved dependency injection system that allows for better management and testing of dependencies.
AngularJS also supports dependency injection but with some limitations compared to Angular.
7) Binding:
Angular uses one way data binding by default, which helps in maintaining a clear data flow and reducing the risk of side effects.
AngularJS uses two way data binding by default, which can make the application harder to debug and maintain in certain scenarios.
8) Tooling and Ecosystem:
Angular has a rich ecosystem of tools, libraries, and resources that support developers in building scalable and robust applications.
AngularJS has a smaller ecosystem compared to Angular and may have limited support in terms of modern tooling and libraries.
9) Updates and Support:

Angular is actively maintained by Google and has regular updates and support for the latest web standards and practices.
AngularJS is in a maintenance mode with long term support for critical bug fixes but lacks new features and updates.
Based on these differences, a training program focusing on Angular would be beneficial for students who want to learn a more modern and in demand front end framework with advanced features, performance optimizations, and a strong industry adoption.
