What is the Difference between Angular and Angular JS ?

AngularJS is Google’s open-source JavaScript framework for developing front-end applications. The following versions were numbered from Angular 2. AngularJS was part of the JavaScript ecosystem and was immediately welcomed by web developers. It was the first structure for the development of interactive websites. This led to the development of very responsive single-page applications with an excellent user interface.

What is the Difference between Angular and AngularJSAngular is the second most common technology in structures, libraries, and other technologies. Here, Angular includes AngularJS and Angular. 36.9% of surveyed engineers agreed to use AngularJS or Angular 2+ to create impressive user interfaces.

In the same survey, 46% of respondents said that Angular was one of the most feared executives. This blog will see the Angular vs. AngularJS debate that has divided the developer community since Angular 2 was launched in 2016.

Whether you are a software developer looking to branch out into a web development field or a business looking to expand your presence by launching apps, the AngularJS vs. Angular debate should be interesting. Without further ado, come on.

Angular vs. AngularJS: history of Angular Versions

Google launched AngularJS or Angular 1 in 2010. It immediately became popular and supported because static HTML pages can now be designed interactively with AngularJS. However, other structures were launched soon, highlighting the disadvantages of the AngularJS structure.

Due to intense competition from ReactJS and VueJS, Google has completely rewritten Angular 1 for Angular 2 with TypeScript as the new language. The decision to switch from JavaScript to TypeScript was to avoid the pitfalls of JavaScript and introduce a small amount of static typing, a feature required by many web developers.

After Angular 2, Angular 4, 5, 6, and 7 appeared. Of these, Angular 4 is the most popular version and is also backward compatible.

Angular vs. AngularJS: main differences

Angular 2 was a paradigm shift from AngularJS because not only the language but also the underlying architecture and data link approach were changed. However, AngularJS and Angular continue to be used by web developers and developers according to their needs.

Consider the main differentiators between Angular and AngularJS

1) architecture

AngularJS supports the Model View Controller architecture. You paste the business logic into the model, the controller’s desired output, and Angular does all the processing to derive that output. AngularJS automatically generate the model pipelines.

On the other hand, components and guidelines are the cornerstones of Angular. The details are nothing more than instructions with a predefined model. They provide a modern framework for applications and make it easier to create and manage larger applications.

2) TypeScript

As mentioned earlier, AngularJS uses JavaScript, but Angular 2 and later (summarized as Angular 2+ for discussion) use TypeScript. TypeScript is the superset of JavaScript and provides static typing during the development process. Static typing not only improves performance but also avoids many runtime problems that make using AngularJS difficult for larger, more complex applications.

3) dependency injection (DI)

AngularJS and Angular use dependency injection, but the way they do it is entirely different. In AngularJS, the DI is inserted in several login functions, control functions, and policy definitions.

4) CLI Angular

Angular 2+ comes with its command-line interface or CLI. It is used to generate components, services, etc. and even complete projects quickly and efficiently. You can easily generate different versions of the same task for other platforms with dynamic verification of type, fluff, etc. AngularJS does not have its own CLI.

5) Syntax of an expression

When it comes to a data connection, Angular is more intuitive than AngularJS. An AngularJS developer must remember the correct ng directive for linking a property or event. In the case of Angular, the language uses () for the association of events and [] for the association of properties.

6) Performance

Angular is much faster than AngularJS. The developers claim that Angular applications can be up to five times faster when created correctly than AngularJS applications.

The two-way link that made the original JS Angular popular among web developers has been reversed as it develops increasingly complex applications. To guarantee and implement the bidirectional link, AngularJS continues to validate each scope variable with its previous value using a summary cycle. This digestion cycle is carried out randomly. As the program size increases, the review may continue indefinitely, which affects the application’s performance.

On the other hand, Angular has a flow architecture in which the detection of changes is done through a unidirectional data flow, making applications much faster.

7) Mobile support

AngularJS does not support mobile development, unlike Angular. This makes AngularJS a little antediluvian in the age of mobile computing.

Angular vs. AngularJS

Angular and angular JS have their advantages and disadvantages. Here we list so that you can make your own decisions based on your specific needs.

Angular: advantages

  • Angular is at least five times faster than AngularJS, thanks to a much better data connection algorithm and component-based architecture.
  • An Angular application’s components are entirely independent and independent, which makes them reusable and easy to test.
  • Angled applications can be rendered on browsers and mobile devices.
  • Angular has built-in extensions to render server-side applications. This allows developers to synchronize client and server content, a significant advantage for SEO.
  • Angular supports slow loading, which speeds up applications because only the necessary components are loaded.
  • The first angled approach to TypeScript ensures cleaner code, better navigation, and a high-quality product.

Angular: disadvantages

  • The angular learning curve is steep, as you must also be proficient in typing, a static type language. With the advent of frameworks for rapid development, many developers are not statically compatible.
  • Since Angular 2 was a completely new version of AngularJS, legacy systems developed with AngularJS need to be migrated, many developers don’t like.
  • Angular is sometimes called a complex language because the components are handled in a very complicated way.
  • The angled command-line interface is very popular with engineers, but they also complain that the documentation is incomplete.

AngularJS: advantages

  • Since it is based on JavaScript, learning AngularJS is much easier and faster.
  • AngularJS bidirectional data connection allows for quicker and more accessible data connection without developer intervention.
  • AngularJS supports faster coding and prototyping and dramatically reduces development times.
  • AngularJS MVC and MVVM architecture separate design data, making it easier to develop and maintain complex Web applications.
  • With clean and organized coding, AngularJS codes can be reused to a high degree.

AngularJS: disadvantages

  • If JavaScript is disabled on the system trying to run the AngularJS application, the application will not run on it.
  • Developers must be familiar with the MVC architecture to use AngularJS.

Should I choose Angular or AngularJS?

If you look at Angular’s long list of benefits, it makes sense to choose Angular instead of AngularJS. However, it would help if you did not forget Angular’s steep learning curve. If you need to develop a relatively simple and straightforward application, AngularJS can make development faster and easier. However, if you want to build complex applications that need to be scalable, Angular should be your obvious choice.

Considering Angular’s steep learning curve, you can hire Angular developers or Angular development companies to make your job easier. As a developer or business owner, investing in Angular would be a positive step in the right direction.

Angular vs. AngularJS: final words

When AngularJS was first launched, Web developers became increasingly popular for its built-in features, such as a two-way link, the ability to develop responsive Web applications, and responsive designs. However, the drawbacks were highlighted when other front-end development frameworks, such as ReactJS, were introduced and performed better. As mentioned earlier, AngularJS has been rewritten in Angular 2 to provide a better alternative for web developers.

Currently, Angular offers the best alternative for creating large and complex applications. The Google development team is working to reduce the build size of Angular applications and improve their performance.

Angular is the structure of the future. Google switched to TypeScript to improve code maintenance and overall application performance. Angular now appears to be focused on enterprise-level application development.

Syntactic expression

AngularJS forces developers to remember many predefined commands to perform actions such as linking. For example, the ng-model can create a bidirectional link, while ng-bind can be used for the unidirectional counterpart.

These actions are simplified in Angular. The ng-Model command is a single command used for all of these purposes.


In summary, we can say that AngularJS is more suitable for small web applications and Angular for large companies. It would help if you experimented with both frameworks before deciding which one is best for your particular application. Knowing both is an advantage.

In the end, what matters is the importance of the resources and support available with third-party models and components.
