It's obvious, if you starting your career in web development, or trying to pick a framework for your next project, people always have a problem and that is mostly what to pick:- Angular or React
So, let's cut the chase and I will tell you the 5 most important differences between Angular and React, and it will definitely help you to know which web framework to use React or Angular.
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.
Winner: React
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.
Winner: Angular and React (Depends on Type of application)
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 incompatibility. 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.
Winner: Angular
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.
Winner: React
5. Testing
AngularJS 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.
