What is the difference between Angular and AngularJS?

Angular and AngularJS are both languages ​​for web application developers. Angular is based on Typescript as an alternative, but AngularJS is often used to develop web-based dynamic applications. Angular is a frequently used upgrade version today. Some of its key attributes include ease of use, a highly modular structure, and high speed compared to AngularJS.

AngularJS, on the other hand, is based on Javascript and is used as the standard developer for all Angular v1.x subtypes. This mode was first created in 2009 and is commonly known as Angular 1. This is an open source app development framework that allows you to change the static base of HTML to a dynamic version of HTML. It also comes packed with various directors and filters. The latest upgraded Angular version is Angular 9, and the current stable version of AngularJS is 1.7.7.

Evolution from Angular version

In 2010, Google released Angular1 or AngularJS. It was so helpful in turning a static HTML page into an interactive interface that it quickly gained a lot of popularity and support.

This highlights the limitations of the previously developed AngularJS framework. Due to the fierce competition between VueJD and ReactJS, Google chose to completely rewrite Angular 1 to Angular 2 by replacing javascript with TypeScript as a new programming language. Google’s move to replace JavaScript with TypeScript was done to avoid the pitfalls that could cause the framework to fail due to its reliance on JavaScript. Google also wanted to introduce a small amount of typing in the static style that many modern web developers were looking for.

After Angular 2, they designed Angular 4, 5, 6, and 7. Angular4 was the most popular of these versions because of its taste and backward compatibility.

Angular and AngularJS: Differences

The main difference between AngularJS and Angular is that AngularJS is based on JavaScript and Angular is based on TypeScript. These frameworks have a lot in common because they are open source, front-end, and platform-accessible routes used to create dynamic SPAs. However, there are differences that affect their usefulness.

1. Differences between Angular and AngularJS components

What does it mean that one framework is based on JavaScript and the other framework is based on TypeScript?

There are two main differences:

  • Angular uses the ES6 Typescript superset, which is backwards compatible with ES5. AngularJS, which is based on JavaScript, on the other hand, depends on various scopes and controllers.
  • Angular uses a leveled-up hierarchy of components, while AngularJS relies on directives.

2. How does the use of directives differ between Angular and AngularJS?

Both AngularJS and Angular use directives, but in different ways. Angular has more standard directives. AngularJS, on the other hand, includes those packs. Therefore, users need to be careful when using directives. For example, if you want to build dual bindings in AngularJS, you need to rely on ng-model. Conversely, ng-bing is used for one-way binding.

Only models can be found in Typescript Angular. The symbols used for one-way binding are:[], And for bidirectional binding, you can use the following characters:[()]” When “[]”” For property bindings. You can use “()” for event binding purposes.

AngularJS architectural structure for Angular

1. Angular JS

The AngularJS framework has an MVC or model view controller that acts as the main component by managing logic, data, rules, and application behavior. The breakdown of MVC is as follows.

  • model: Where to collect all stored data
  • opinion: Output of information on reviewed models
  • controller: Takes input, converts them into commands, and uses this processed information model And that look..

2. Angle

For Angular, use directives in component-style templates. There are two main types of directives for using Angular.

  • Structure directive: It modifies the entire DOM layout by replacing internal elements.
  • Attribution directive: These change the behavior of the DOM and the appearance of the elements.

Differences in mobile support: AngularJS and Angular

AngularJS cannot provide mobile support, but Angular does support mobile applications.

1. Speed ​​and performance

AngularJS Has a two-way binding feature that ultimately reduces the time and effort required for construction. Angular There is an upgraded framework with an improved structure to improve speed and performance.

2. Tool support

  • Angular Use the CLI or command line interface to reduce the time it takes to create your application.
  • AngularJS, on the other hand, A framework that relies on third-party tools such as WebStorm and IDEs.

Angular’s benefits over AngularJS

Here are the benefits of Angular over AngularJS-

1. Dynamic loading

Angular has a combination of several asynchronous templates and additional programming support.

2. Modularity

Angular’s main functionality has moved to various modules that run on faster, lighter cores.

3. Ahead-of-Time or AOT

This kind of compilation helps convert Typescript and HTML to JavaScript during the build-time process. AOT primarily compiles all the code, and the browser loads it along with the compiled code for faster q-rendering.

4. CLI

Angular has a CLI or command line interface to help you deliver and create smoother applications. It also engages in project construction and provides a more accessible interface for testing.

5. Architecture

Angular’s architecture helps to separate logical and functional components from each other.

6. Dependency injection factor

The best part is that Angular is based on one-way change detection. Instead of using directives similar to AngularJS, Angular uses hierarchical dependency injection, which greatly improves the performance of the framework.

7. Language

Angular is written primarily in TypeScript, but you can choose another language from Dart, ES5, and ES6. These are also used for code development.

8. Routing

The routes used by the Angular framework are very simple and user-friendly. You can also interpret the URL as a directive and go further to the client view interface.

Benefits of AngularJS over Angular


  • AngularJS’s Model View Controller speeds up application development through data binding.
  • With a bidirectional data binding process and a POJO model that provides a definitive interface, users can use less code in their projects.
  • AngularJS also has a continuously updated and automated unit testing feature.
  • AngularJS also offers a very comprehensive solution for all front-end development. This is because AngularJS does not rely on additional plugins or other frameworks.
  • Using HTML as the AngularJS declarative language is very intuitive to use.
  • The AngularJS framework has reusable components.
  • AngularJS has become a great framework due to its simpler architecture and smoother functionality for mobile and web app development.

Despite the differences in ease of use, compatibility, and speed, both AngularJS and Angular have their advantages. Google maintains both frameworks so that both can continue to support the popular community. Many users still prefer Angular because of the dynamic capabilities of creating mobile and web applications and the single-page capabilities of HTML and TypeScript. Basically, it depends on what the developer needs the application for.
