The internet keeps changing every day, and so does the technology running it. No matter how little these changes are, developers have to adapt to them to remain in business. Angular is one of them. Angular has undergone significant changes in the last few years. Google created angular in 2009, and in 2012 version1.0 was released. Angular has dominated the open-source industry JavaScript frameworks, and many people and companies have adopted this technology. This has led to Angular changing from the AngularJS version 1.0 to Angular version 2.0. It’s the latest version is Angular version 4.0, and all these changes have occurred in less than five years. However, many in the Angular community are slow in accepting newer versions. In this article, I am going to explain the various changes made in Angular and why you should migrate to the latest version. We are also going to give you absolute differences between Angular vs. AngularJS to help you make a wise choice.

Angular
Founded by Google, Angular is a powerful and popular JavaScript framework used to develop web applications. The majority of front-end developers use Angular and other structures like React to present data effectively. The newer versions are more efficient than the older ones since core functionalities were moved to different modules, leading to high speeds and seamless transitions. The newly added Angular CLI allows you to create a scaffolding of your Angular project.
AngularJS
AngularJs, on the other hand, is a front-end JavaScript framework that is popularly used to create SPAs or single-page web applications. What I like about this framework is its rapid growth and expansion that allows web developers to build enhanced web applications. It changes the static HTML to dynamic HTML. Developers don’t have to code using AngularJS to become its dynamic binding, and the dependency injection feature has taken care of that. Since AngularJs is evolving very fast, there are many versions of this framework. The latest version one is 1.7.7.
Angular and AngularJs are not the same. AngularJs is an open-source project meaning it’s free to use, and anyone can modify it. The framework extends HTML attributes with Directives, and data is bound with HTML.

Significant Differences between Angular vs AngularJS
Below is a list of points describing differences
1. Architecture
AngularJS: TheAngularJS framework supports the Model View Controller or MVC architecture. The developer puts the business logic in the model and the desired output in the controller. AngularJs then does the processing to derive that output. The framework automatically generates model pipelines.
Angular: Compared to AngularJS, the building blocks in Angular are formed by components and directives. Parts are Directives with predefined templates. Elements make it easier to create and maintain larger applications by providing a modern structure.
2. Language
AngularJS: AngularJS is written in JavaScript.
Angular: On the other hand, Angular uses the TypeScriptlanguage, which is also used by Microsoft’s. This language is a superset of ECMAScript 6 (ES6). Some of the benefits that come with this combination are type declarations from TypeScript and iterators & lambdas from ES6. The recent version of TypeScript has robust type checking, and objects oriented features and is compatible with Angular 4.
3. Expression Syntax
AngularJS: If you want to bind an image, property, or an event, you will need the right ng directive.
Angular: When it comes to event binding, Angular focuses on “( )” and “[ ]” for property binding.
4. Angular CLI
AngularJS: AngularJS doesn’t have its own CLI.
Angular: Angular, on the other hand, has its command-line interface or CLI that generates components, services, and more, which also helps to complete projects faster and efficiently. It simplifies the generation of different versions of the same project but different platforms with linting, dynamic type checking, and more.
5. Mobile Support
AngularJS: Since it was designed for a different purpose, AngularJS doesn’t have mobile support.
Angular: Things are different in Angular 2 and 4 since they hold the functionality part of the platform, which includes mobile support.
6. Routing
AngularJS: Routing is configured with $routeprovider. When (). in AngularJS.
Angular: Angular uses @RouteConfig{(…)}, for rout configuration.
7. SEO Optimized
If you want to develop SEO optimized applications, rendering of the HTML at the server-side is necessary in AngularJS. That is no longer necessary in Angular 2 and 4.
8. Performance
Originally, AngularJS was meant for designers and not developers. A few modifications were made when designing AngularJS. However, these changes were not enough to develop web apps efficiently. Newer versions of Angular 2 and Angular 4 were updated to provide a better performance, which focused on speed and dependency injection.
- Speed
Development time and effort significantly reduced in AngularJS when2-way binding was introduced. Page load, however, took considerable time due to more processing on the client-side. With Angular 2, developers can easily create and maintain large applications since it is well structured. This also enhances the change detection mechanism. However, Angular 4 is the fastest version compared to other versions of Angular. - Dependency Injection (DI)
Hierarchical Dependency Injection system is used in Angular, and it implements unidirectional tree-based change detection, which greatly improves the framework’s speed.
9. Animation Package
AngularJS: In AngularJS, the code needed for animation is included in the application, whether it’s necessary or not.
Angular: Animation is packaged separately in Angular, and the developer doesn’t have to download large files.

Should I choose Angular or AngularJS?
Since Angular has lots of benefits compared to AngularJS, it is the better option. However, it has a steep learning curve compared to AngularJS. AngularJS is the perfect option if you want to develop simple and straightforward web applications since it makes the development process more comfortable and much faster. Angular provides the best environment for developing sophisticated and scalable web apps.
To get the best results, when using Angular, I suggest hiring anAngular development company or Angular developers, since it has a steep learning curve. Angular will give you high returns and value for your investment, if you are a business owner or a web application developer.
AngularJS vs Angular: Final Words
What made AngularJS a robust framework preferred by many developers when it was first released, were its excellent features such as the ability to create highly responsive web apps and designs, and two-way binding. However, ever since advanced frameworks like ReactJS were introduced to cater to front-end development, many developers damped this framework. These frameworks perform better than AngularJS.
The best alternative framework for creating complicated and huge web applications right now is Angular. Moreover, plans are underway to further improve the performance of Angular by reducing the build size of its forms.
It is clear is that the Angular framework is here to stay and has a bright future. The reason why Google switched to TypeScript when developing Angular was to improve its overall performance and to make the framework maintainable. It is now designed to also cater to enterprise-level applications.
Building web applications using ReactJS is easy since the frame has a simple learning curve; it is easier to deploy and quite maintainable. However, it gets harder to use this framework when the complexity and size of an application grows. On the other hand, the stability and technical support of Angular make it the best structure for all projects despite its steep learning curve. Google has further improved its longevity by pledging long term support (LTS), making it perfect for scalable and resource-intensive projects.
