Difference Between Angular and AngularJS

For front-end developers, Angular is a popular open-source framework for building web applications. Someone choosing to use Angular gets two options: the choice between Angular and AngularJS. So, let's start with understanding what Angular and AngularJS are.

1. What is Angular?

Angular is a front-end, open-source JavaScript framework written in TypeScript. Google maintains Angular and provides strong standard back-end support for developers to work within it. Angular uses HTML syntax to define the components of the program clearly. It helps developers to build large applications in a maintainable and feasible manner. Angular has come with the core functionality moved to different modules. That is the reason it is faster and smoother than the older one. It has a newly added angular CLI and a new command-line interface.

2. What is AngularJS?

AngularJS is a JavaScript-based front-end open-source framework and is mainly used to develop single web page applications. It helps enrich the static HTML to the dynamic HTML. It extends the existing HTML by providing different directives. The latest stable version is 1.7.7. It has features like dynamic binding and dependency injection that help eliminate the need for code that otherwise had to be written ourselves. AngularJS extends HTML attributes with Directives, and the data is bound using HTML.

Differences between Angular JS and Angular

The table below shows a few major differences between AngularJS vs Angular:

Sr. No.	Key	AngularJS	Angular
1	Interface	AngularJS works on Model View Controller Design. Here, “View Now” shows the information present in the model, and the controller processes the code.	Angular makes use of components and directives. Here, the component is a directive with a template.
2	Language	The code is written in JavaScript.	Here the code is written in TypeScript.
3	Expression syntax	{{}} are used in binding data between view and model. New special methods like ng-bind can be used to do the same too.	() and [] attributes are used to bind data.
4	Model view controller	Uses data binding to speed up the application development.	No MVC.
5	POJO Models	The use of two-way binding and POJO Models Provide a conclusive interface that uses less code in projects.	No POJO Models to make the code short and less.
6	Project Building	AngularJS uses IDE and Webstorm, which are third-party Javascript tools.	Angular uses Command Line Interface for project building.
7	Language	AngularJS uses HTML which is very intuitive.	HTML isn’t used.
8	Modularity	AngularJS has the older version and not a lot of modularity.	A lot of core functionality is moved in different modules in angular. It helps provide a faster and lighter core, asynchronous template compilation, dynamic loading, and added strong support for reactive programming.
9	Directives	Changes in directives. Ng-model means to create a two-way binding and ng-bind for one-way binding.	ngModel is only used. “[ ]” is used for one-way binding. “[( )]” is used for two-way binding.
10	Dependency Injection	DI is not used.	A Hierarchical DI system is used.
11	Management	The project is difficult to manage because of the large size of the source code.	The code is better structured, making it easy to create and manage bigger projects.
12	Mobile	It is not mobile-friendly.	The applications are mobile-friendly.

Conclusion

Angular and AngularJS are different, but each has advantages of its own. Both frameworks are maintained by Google, so there is considerable community support. Weighing the pros and cons according to your needs, you can decide which is better for you.
