Introduction
Angular and AngularJS are two frameworks that are widely used for building web applications. However, there is a significant difference between the two frameworks that developers should be aware of. AngularJS, also known as Angular 1.x, was released in 2010, while Angular, also known as Angular 2+, was released in 2016. In this article, we will explore the differences between Angular and AngularJS.
Architecture
The architecture of AngularJS and Angular is significantly different. AngularJS uses a Model-View-Controller (MVC) architecture, while Angular uses a component-based architecture. In AngularJS, the MVC architecture is implemented using two-way data binding, which means that changes made to the view are automatically reflected in the model and vice versa. On the other hand, Angular uses a unidirectional data flow, which means that data flows only in one direction, from the component to the view.
Performance
Angular is faster than AngularJS in terms of performance. The reason for this is that Angular has a faster change detection mechanism, which means that it can detect changes in the view more quickly than AngularJS. Angular also uses Ahead-of-Time (AOT) compilation, which means that the application code is compiled before it is executed, resulting in faster load times. On the other hand, AngularJS uses Just-in-Time (JIT) compilation, which means that the application code is compiled at runtime, resulting in slower load times.
Language
AngularJS is written in JavaScript, while Angular is written in TypeScript. TypeScript is a superset of JavaScript that adds additional features such as strong typing, which helps developers catch errors early in the development process. TypeScript also provides better tooling support than JavaScript, which makes it easier for developers to work with.

Directives
AngularJS uses directives to manipulate the DOM, while Angular uses components to encapsulate functionality and manipulate the DOM. Directives in AngularJS are more complex and can manipulate the DOM directly, while components in Angular are simpler and provide a more structured way to manipulate the DOM.
Dependency Injection
Dependency Injection (DI) is a design pattern that is used to manage dependencies between objects. AngularJS uses a simple DI system, while Angular uses a more advanced DI system that is based on TypeScript. The DI system in Angular is more powerful and flexible than the one in AngularJS, which makes it easier to manage dependencies and create reusable components.
Routing
Routing is the process of determining which view to display based on the URL. AngularJS uses the ngRoute module for routing, while Angular uses the @angular/router module for routing. The router module in Angular provides more features than the ngRoute module in AngularJS, including lazy loading.
Mobile Support
Angular has better mobile support than AngularJS. This is because Angular has a responsive design, which means that the application can adapt to different screen sizes and resolutions. Angular also has better touch support than AngularJS, which makes it easier to develop mobile applications.
Community Support
Angular has a larger and more active community than AngularJS. This is because Angular is a newer framework and has gained more popularity than AngularJS. The larger community of Angular developers means that there are more resources available, including documentation, tutorials, and libraries.

Conclusion
In conclusion, Angular and AngularJS are two frameworks that are significantly different from each other. Angular has a component-based architecture, is faster, is written in TypeScript, uses components instead of directives, has a more advanced DI system, uses a more powerful routing module, has better mobile support, and has a larger and more active community.
Developers who are new to these frameworks should take the time to learn the differences between the two frameworks. AngularJS may still be a viable option for some legacy projects, but for new projects, Angular is the way to go.
However, it is worth noting that there are some similarities between Angular and AngularJS. For example, both frameworks are open-source and are maintained by Google. They also share some syntax and concepts, such as templates and data binding. This means that developers who are familiar with AngularJS may find it easier to transition to Angular.
In conclusion
In addition, both frameworks have their own strengths and weaknesses. AngularJS may be easier to learn for developers who are new to web development, as it has a simpler architecture and uses JavaScript, which is a widely used programming language.
Overall, the choice between Angular and AngularJS will depend on the specific requirements of the web development project. Developers should consider factors such as performance, scalability, ease of use, community support, and mobile support.
while AngularJS and Angular may share some similarities, there are significant differences between the two frameworks. Angular is a more advanced framework that provides better performance, a more powerful architecture, and better mobile support than AngularJS. Developers should carefully consider their requirements before choosing between the two frameworks. Hope this Article is informative and usefull for our readers!
