Hello, people! Nowadays many people want to read topics about “Why You Should Upgrade AngularJS to Angular”. Now, I’ll be taking a closer look at this. If you are thinking whether you should upgrade AngularJS to Angular for your web applications, the answer is yes, and now it is the time to leap. AngularJS became a favorite among the web app developers almost instantly and it has covered the way for a new era of single-page applications with high responsiveness. Our article aims to highlight the difference between AngularJS and Angular. It will help to explain why migrating from AngularJS to Angular is important for building better user interfaces. I would be grateful if you could spare me a few minutes.
So, let’s read this article!
AngularJS vs Angular: Should You Upgrade AngularJS to Angular?
According to different experts, AngularJS is an open-source framework for front-end development. It helps to create dynamic single-page applications. It goes without saying, it is based on features, such as two-way binding, modularization, templating, mobile support, dependency injection, material design, and reactive programming. The latest versions of Angular help to fix the challenges with AngularJS architecture, such as the concept of scope and the administration of controllers. Currently Angular presents the best choice for building large and complex applications. The development team at Google is working towards decreasing the build size of Angular applications and improving their performance. Angular is the framework for the future. Google moved to TypeScript in order to develop the maintainability of the code as well as the overall performance of applications. Angular now seems prepared towards enterprise-level application development.
Difference Between AngularJS and Angular
So what’s the difference between AngularJS and Angular? Before I dive into the differences, let’s first clarify each version with a description:
AngularJS
It is an open-source, JavaScript-based, front-end web application framework for progressive web app development. It uses HTML as a template language. By continuing HTML characteristics with directives and required data to HTML with words, AngularJS creates an environment that is simple, especially strong, and quick to develop.
Angular
As for Angular, it is the comprehensive term used to apply to Angular 2, Angular 4, and all other versions that come after AngularJS.
At this point, I want to compare architecture, language, expression syntax, mobile support, and routing.
| AngularJS | Angular | |
| Architecture
|
The architecture of AngularJS is based on the model-view-controller design. The model is the central component that expresses the application’s behavior and manages its data, logic, and rules.
|
It should be noted that in Angular 2, controllers and scope were followed by elements and directives. Let’s discuss what components are. Components are directives with a template. They deal with a view of the application and thought on the page.
|
| Language
|
AngularJS is written in JavaScript.
|
Angular uses Microsoft’s TypeScript language.
|
| Mobile Support
|
AngularJS was not built with mobile support in mind. | But Angular 2 and 4 both feature mobile support.

So, my dear readership you’ve read the differences between AngularJS and Angular. And of course I want to tell you the advantages and disadvantages of them. Let’s move to the next point.
Advantages and Disadvantages
As everyone knows, each version has its own advantages and disadvantages. Let’s read about it.
AngularJS
Advantages
- It provides the unit testing ready.
- It has a great MVC data binding that offers a faster app development.
- Using HTML as a declarative language makes it very natural.
- It is a general solution for rapid front-end development since it does not need any other frameworks or plugins.
- AngularJS apps can run on every important program and advanced cells including iOS and Android-based phones and tablets.
Disadvantages
- It is big and difficult due to the many ways of doing the same thing.
- Implementations compare unsuccessfully.
- If a user of an AngularJS application damages JavaScript, nothing but the basic page is obvious.
- There’s a lagging UI if there are more spectators.
Angular
Advantages
- TypeScript provides code optimization.
- It is mobile-oriented.
- It has developed dependency injection and modularity.
- It gives more opportunities for languages such as Dart, TypeScript, ES5, and others.
- It gives simpler routing.
Disadvantages
- It is more difficult to set up compared to AngularJS.
- It’s ineffective if you only need to create simple, small web apps.
So, I tried to explain to you the most important information about AngularJS and Angular. I hope you understood all these facts. It should be noted that Angular 1 gave high potential to build products according to the latest trends, which made it popular among developers all over the world.
Main rules to follow when upgrading to Angular from AngularJS
- Certainly, your procedure should depend on the scope and complexity of an application.
- Some apps may seem to be simple for AngularJS to Angular updates while others will need a lot more work to do.
- You require to be well-prepared for migrating from AngularJS to Angular 2.
- You ought to know how you should structure your AngularJS code to align it with Angular, as the following includes the best parts of the former.
To make the conversion from Angular 1 to Angular 2 uncomplicated and gradual, stick to these easy rules:
- Keep one component per file for available navigation and successful migration between the frameworks.
- Make sure that multiple parts of an application are located in different lists and modules.
- Structure your app layer upon layer to import one part at a time. If your application doesn’t look like this yet, we advise you to take notice before getting started with an upgrade.
Summary
To sum up all the information, I can say that these facts can also influence your choice but any framework you choose will be surely useful for you. I truly hope this topic “Why you should upgrade AngularJS to Angular.” I’ve provided enough information due to this theme.
I tried to compare the two frameworks and how they work, as well as their advantages and disadvantages. I hope, with all my heart, you enjoyed this topic and picked a lot of information, which will help in your future.
