Various differences between Angular and AngularJS are stated as follows:

Architecture - AngularJS supports the MVC design model. Angular relies on components and directives instead

Dependency Injection (DI) - Angular supports a hierarchical Dependency Injection with unidirectional tree-based change detection. AngularJS doesn’t support DI

Expression Syntax - In AngularJS, a specific ng directive is required for the image or property and an event. Angular, on the other hand, use () and [] for blinding an event and accomplishing property binding, respectively

Mobile Support - AngularJS doesn’t have mobile support while Angular does have

Recommended Language - While JavaScript is the recommended language for AngularJS, TypeScript is the recommended language for Angular

Routing - For routing, AngularJS uses $routeprovider.when() whereas Angular uses @RouteConfig{(…)}

Speed - The development effort and time are reduced significantly thanks to support for two-way data binding in AngularJS. Nonetheless, Angular is faster thanks to upgraded features

Structure - With a simplified structure, Angular makes the development and maintenance of large applications easier. Comparatively, AngularJS has a less manageable structure

Support - No official support or updates are available for the AngularJS. On the contrary, Angular has active support with updates rolling out every now and then

Let's compare the features of AngularJS and Angular in a tabular form:

It is popularly known as AngularJS.The later Angular versions were a complete rewrite of AngularJS. For example, Angular 2 was initially released in 2016. There is nothing common between Angular2 and AngularJS except the core developer's team. After that, Angular 6, Angular 7, Angular 8, Angular 9, and Angular 10 were released that are very similar to each other. These later versions are known as Angular.

RoutingIn AngularJS, $routeprovider.when() is used for routing configs.In Angular, @RouteConfig{(?)} is used for the routing config.
StructureIt is the first and basic version, so it is very easy to manage.It has a very simplified structure that makes the development and maintenance of large applications very easy.
SpeedIt is slower because of its limited features.It is faster than AngularJS because of its upgraded features.
