As far as you know, AngularJS is a front-end web framework with open-source code. It was launched in 2010. Angular is also an open-source web application framework. It was created in 2016. Angular is a complete rewrite from the same program that built AngularJS. If you are a developer, you must constantly monitor updates and innovations in the field of IT. Today I will tell you about what reasons and features to migrate from AngularJS to Angular are and what are the differences between both these frameworks.
What is the difference between AngularJS and Angular?
First of all, AngularJS is based on JavaScript, and Angular is based on TypeScript. Accordingly, these two frameworks have a difference in components. For example, AngularJS uses terms of scope and controllers, and Angular uses a hierarchy of components. In the second place, AngularJS is based on components and AngularJS uses directives. Angular and AngularJS use Directives, but Angular uses standard Directives, and AngularJS has a pack of them. One of the main differences is mobile support. AngularJS maintains mobile support in contrast to Angular. Angular is created for building web applications. AngularJS for building single-page applications.
What are the reasons to migrate from AngularJS to Angular?
1. Architecture
AngularJS uses terms of scope and controllers. They are a little bit stiff and less reiterated. AngularJS uses a hierarchy of components. As for me, it is better. It lets reclaim repeatedly the elements that ameliorate their checkability and serviceability. Angular has more independent components.
2. Structure
AngularJS is supple but doesn’t so stable and doable. Angular uses another method. Angular imposes an organized mode based on components. It is all done in an accurate way to exchange data between components. In this way, creating and supporting bigger applications is more complex in Angular.
3. Language
Begin with the fact that AngularJS uses JavaScript. It simplifies the process of creating a project. But there is also a disadvantage. AngularJS doesn’t have the function of the type-checking and because of this, compilation of errors goes unnoticed. In comparison with AngularJS, Angular has more benefits because of the use of the TypeScript language. TypeScript is consistent and ductile. These benefits help to optimize the code, reduce execution errors, and run on many platforms.
Furthermore, TypeScript gives a possibility of backward compatibility with JavaScript. It offers superior security and helps to define errors at an early stage while writing the code. In case, if you don’t know TypeScript and don’t want to learn it, you can write the code with the help of JavaScript.
4. Mobile Support
As I mentioned above AngularJS has no mobile support. It is quite strange. Why can’t the framework provide mobile support in the 21century?
Angular is the best choice for creating any type of mobile application. All the Angular 2+ versions maintain mobile support. Of course, you can also use Angular for creating a web application.
5. Material Design
Angular has a better user interface than AngularJS. For example, Angular 5 has a set of the component development kit (CDK). It is the core of the Angular Material component library and it gives the possibility for developers to create their elements. Another version, Angular 7, combined with the elements of Material Design and it allows you to build responsive and multiplatform applications.
6. Data Binding
AngularJS has a two-way data binding and because of this development with this framework has a significant advantage. As for versions of Angular 2+ and others, they have the introduction of binding properties, events, and templates. The overall application performance and speed of the program become better through data exchange.
7. Expression Syntax
In Angular, you can bind an event using () and a property using [].In AngularJS you need more effort. You should know and remember the exact ng directive for desired results. Therefore, the structure of Angular is more representative in terms of data binding compared to the AngularJS structure.
Conclusion
To sum up, Angular is better than AngularJS. AngularJS goes away because it is already a bit old and does not have as many new and good features that developers need nowadays. Today Angular is more popular among JavaScript interface frameworks.
