Angular
Angular is a well-known framework for building web applications among
most of the front-end developers.
AngularJS
AngularJS is an open-source JavaScript framework
for developing front-end applications.

Angular vs. AngularJS: Major Differences
TypeScript
AngularJS uses JavaScript. On the other hand, Angular 2 and its latest
versions use TypeScript. TypeScript is a JavaScript superset and
provides static typing during the development process.
Architecture
The AngularJS architecture is based on the
Model View Controller (MVC) design. Models are
the main components that define the
application's behavior and manage their data,
logic, and rules.
In contrast, components and directives form the building
blocks of Angular. Components are no more than
directives with predefined templates.

Angular CLI
Angular 2+ renders with its own command-line interface or the
CLI. It is used to produce components, services, etc. and also
complete projects quickly and effectively. On the other hand,
AngularJS does not have its own CLI.
Dependency Injection (DI)
Both AngularJS and Angular use dependency injection but the
way they perform actions are completely different from each
other. In AngularJS, DI is incorporated into various link functions,
controller functions, and directive definitions.
Expression Syntax
When it comes to data binding, Angular is more spontaneous
than AngularJS. AngularJS developers must use the correct
directive for binding a property or an event.

Performance
Angular is much faster than AngularJS. In fact,
the developers say that if angular applications
are built correctly they can be up to five times
faster than AngularJS applications.
Mobile Support
AngularJS does not support mobile development,
but Angular does.

Advantages and Disadvantages
● Angular is up to five times faster than AngularJS because the data binding algorithm and
component-based architecture are much better.
● The Angular application components are independent and self-sufficient that makes them
reusable.
● Angular applications can be rendered on browsers and mobile devices.
● Angular supports delayed loading, which makes the applications run faster because only the
required components are loaded.

Disadvantages of Angular
● The learning curve of Angular is very high because you also
have to master TypeScript.
● With the emergence of a framework that allows rapid
development, many developers are not compatible with
statically typed languages.
● Angular is sometimes known as the verbose language
because the components are managed in a very complex
way.

Advantages of AngularJS
● Based on JavaScript, AngularJS is much easier and faster to learn.
● AngularJS’s bidirectional data binding facilitates enables faster
and easier data binding without developer intervention.
● AngularJS supports faster coding and prototyping, significantly
decreasing development time.

Disadvantages of AngularJS
● If JavaScript is disabled on the system where you want to
run the AngularJS application, the application will not run
on it.
● The developer must be familiar with MVC architecture to
use AngularJS.

If you want to build a fairly simple and straightforward application, AngularJS can make development
faster and easier. But if you are looking to develop complex applications that must be scalable, Angular
should be your clear choice.
Considering that AngularJS is the framework for the future, you can
hire certified AngularJS developers to make your work easier and faster.
