When it comes to web development, we are often confused about the framework we should choose. After all, there are hundreds of them available in the market. But developers often suggest that we should choose the one that’s best suited for us. For this, we must know about the technology and its features.

In this article, we will learn about the pros and cons of the two most demanding services, AngularJS development services, and ReactJS development services.

First, let’s get a brief idea about both the frameworks

● AngularJS

AngularJS is a powerful front-end JavaScript framework used to build dynamic web apps. Google launched it in 2010, and today many big companies like Nike, Apple, PayPal, and Udemy rely on it for their customer experience.

● ReactJS

ReactJS is an open-source JavaScript library, used to develop user interfaces for websites and mobile apps. Launched in 2013, many big companies like Netflix, DropBox, and Khan Academy leverage it, as it has no server-side rendering.

Now, let’s compare AngularJS and ReactJS

  1. DOM (Document-Object-Model)

A DOM is an API that defines the logical structure of the document. It helps in understanding the flow of HTML and XML documents.

AngularJS and ReactJS have different approaches for defining the logical structure. AngularJS has a real DOM, and for every change in the application, it creates a new DOM from scratch and then executes it. ReactJS, on the other hand, has an inbuilt virtual DOM that re-renders only the updated part of the application and executes only the changes instead of reloading the page.

2. Data Binding

Data binding varies according to the usage of the application. If you have an entertainment app that only allows you to view the videos and content, Reacts’ one-way data binding would be profitable. However, if you have a booking or management app, you require a framework that provides two-way data binding like AngularJS.

The difference is that in one-way data binding, any model changes would only affect the view. In two-way data binding, any model change would affect the view and vice versa.

3. Code Compatibility

When it comes to AngularJS development services, it’s easier for developers to update the app to the latest version. Using a command-line interface and the ng_update component, they can instantly upgrade to the latest version.

If you’re going for ReactJS development services, let me tell you, it lags in compatibility. Here, the developers need to use third party extensions for updating and modifying the app components. Also, they need to keep a regular check on the external libraries and whether they are compatible with React’s latest version.

4. Language

AngularJS is a framework and has a lot of features, modules, and complex components. So, the developers have to learn a lot, including TypeScript, RxJS, pipes, and dependency injection, before heading towards the actual development.

ReactJS is a library, and it’s easy for developers to learn it. With a handful of JavaScript knowledge, developers can build apps in React’s ecosystem. Thus, language-wise, ReactJS wins.

5. Testing

We know the importance of testing an app before the final launch. And how great it feels if it done via a single tool.

AngularJS gives us that benefit. It makes app testing possible via a single tool like Protractor, Jasmine, and Karma. Talking about ReactJS, it’s not possible to test an app with a single tool. Being an external library, it depends on multiple tools for testing. For example, Jest for JavaScript code testing, React- unit for unit testing, etc.

Final Thoughts

Both AngularJS development services and ReactJS development services have their own set of advantages and disadvantages. Even developers would prefer the one based on their requirements. So, it is advisable to choose the one that best suits your business needs — for example, ReactJS for small-size apps, AngularJS for enterprise apps.
