AngularJS is a powerful front-end framework that helps developers create robust and efficient web applications. Angular 2 is the next generation of this framework, offering many improvements over its predecessor. In this article, we will take a look at some of the key differences between AngularJS and Angular 2.
First of all, Angular2 is a complete rewrite from the ground up using TypeScript whereas AngularJS was written in Java Script with a dependency on jQuery. This will result in less memory consumption and better performance for angular 2 applications because it is not dependent on an external library like jQuery. In addition, angular 2 has been designed with mobile apps in mind so it becomes easier to build responsive applications that work seamlessly across different devices as well as desktop browsers. In contrast, angularjs does have some built-in support for responsiveness but it is not as well-optimized as angular 2.

What is Angularjs?
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS automatically updates the page as data changes, making it ideal for long-running web applications.
What is Angular 2?
Angular 2 is a complete rewrite of the AngularJS framework. It was first announced in 2014 and it has been in development ever since. Angular 2 is designed to solve some of the problems that were encountered with AngularJS, such as performance and cross-browser compatibility. In addition, Angular 2 offers many new features, such as Components and Directives. In this article, we will take a closer look at what Angular 2 is and how it differs from AngularJS.
10 Differences Between Angularjs and Angular 2
1. Angularjs and Angular 2 are two different frameworks.
2. The first difference between the two frameworks is that AngularJS was designed for use with HTML, while Angular 2 was created to work with TypeScript.
3. Another difference is that the original framework only had one way of doing things, but now there are many ways to do it in this new framework.
4. In addition, the second version has a much more flexible design than its predecessor.
5. There were also changes made to data binding and templating.
6. And lastly, both versions have their own unique set of features and functionalities which make them unique from each other.
7. The third major difference is that there are no more directives in angular 1; everything must be done with components.
8. A fourth major difference between these two frameworks is that angular js has one-way bindings while angular 2 uses two-way data binding.
9. There are also differences when it comes to routing – for example, you need an extra component called ngRoute for routing in the old framework but not so much with the new one.
10. Lastly, another big change is how controllers work – they don’t exist anymore because of structural directives like ngFor.
