Despite the two frameworks being in tight competition, there are noticeable significant distinctions between Angular vs angularjs. For starters, Angular JS was the first framework created by Google as an open-source front-end to develop single-page web apps. Angular runs both on the front and backend side. The language used to write this first Angular is JavaScript, while the Angular framework got rewritten using a different language known as Typescript. The added features gave it a better performance. Let's find more of those essential differences below:

Distinguishing differences between Angular vs. AngularJS

Architecture

• Angular JS: This framework supports MVC design.
• Angular: It works with components and directives.

Command Line Interface (CLI)

• Angular JS: This framework depends on third party CLIs because it doesn't have its own.
• Angular: It has its own CLI that helps it to get the component's services and directives quickly. It comes with a set of commands that are quite convenient to build your projects using the framework.

Language

• Angular JS: It is a framework written in JavaScript language, and uses HTML templates.
• Angular: Written in a TypeScript language, which happens to be a superset of JavaScript, ECMAScript 6 (es6), improves its performance.

Routing

• Angular JS: For routing configuration, the framework uses ()
• Angular: It uses @Route configuration that looks like this; {()}

Structure Management

• Angular JS: The structure of this framework is less manageable when you compare it with Angular. However, it handles the small applications well.
• Angular: It has a better structure that helps to create or manage larger applications.

Dependency Injection

• Angular JS: In this framework, DI gets injected into directive definitions, controller functions, and others.
• Angular: It uses Hierarchical Dependency Injections with declarations, providers, and constructor functions. It helps to boost your app performance.

Mobile Support

• Angular JS: The framework does not have mobile support.
• Angular: It has all popular mobile browser support.

Performance

• Angular JS: The two-way-binding process keeps checking for scope variable, using the digest cycle. The checking may take long, causing the application performance.
• Angular: Being a rewrite of AngularJS, Angular is faster and efficient. Its flux architecture makes applications run faster.

It is good to note that Angular JS uses controllers, while the rewrite of it is component-based. And since the scope of controllers is over, they are replaced by components.

N/B, Angular, does not have backward compatibility with AngularJS.

Angular Features

• Supports data binding
• It has an MVW
• It comes with an inbuilt template engine
• It supports hierarchical Dependency Injection.
• It is a highly scalable framework since it's modern and faster.

If you are still trying to figure out which is better than the other, the pros and cons of Angular vs. AngularJS might be helpful.

Angular: Pros

• Due to its component-based architecture and better data binding algorithm, Angular has faster performance.
• The independent components that this framework uses gets easily replaced or maintained.
• The inbuilt extensions in Angular's server-side allow the developers to sync both front and backside of content.
• The use of TypeScript language results in cleaner code, improved navigation, and top-quality products.
• Applications in the Angular framework can also work on mobile devices and browsers.
• Since Angular's components are independent, they are test-friendly and reusable.

Angular: Cons

• As most developers are not conversant with TypeScript, they find it to have a steep learning curve.
• The management of Angular's components is quite complicated.
• Although most engineers appreciate the command-line interface, they do complain that the documentation is incomplete.

Angular JS: Pros

• JavaScript, which is the language used in this framework, makes it easier for developers to learn the structure.
• AngularJS architecture of MVC and MVVM separates the design and data, making the complex web development more straightforward.
• Organized coding makes the framework's codes reusable.
• There is faster coding support and prototyping in AngularJS, which results in improved development time.

Angular JS: Cons

• A developer who is not familiar with an MVC architecture, cannot use this framework.
• A developer can only use the system with JavaScript; if it gets disabled, it cannot run.
• The DI feature and directives can get complicated to a developer used to traditional methods. One spends a lot of time learning or ends hiring someone knowledgeable.
• If you are new in the framework, you will find the scopes debugging to be quite complicated.

In conclusion, you can see a lot of improvement in Angular. It is faster and more efficient. So, Angular vs. AngularJS, which one to pick? As per the StackOverflow Developer Survey done in 2018, both were second-most-used-technology in Libraries and frameworks. Although the number may have changed, 36.9 percent of engineers said they were using both Angularjs to create dynamic user interfaces.
