If I have to determine what is React then I would suffice that it is a popular front-end library that helps developers build feature-rich and interactive sites with both less time and effort.
ReactJS is one of the most widely used open-source Javascript libraries. It was developed by Facebook and Instagram to help developers build web applications more easily. They already use ReactJS to build scalable, interactive user interfaces. And that’s not it, many top brands enjoy various benefits of using React JS for your development project. This javascript library can come in quite handy when you want to get things done with less time and effort.
But some experts in the industry warn professionals against using this library for app development because of some of its serious drawbacks. And that led to the debate about whether ReactJS is a good choice for software development or not.
Hence, in this article, we’ll take a look at some of the pros and cons of ReactJS. So you can decide for yourself if ReactJS is the right choice for your business or not.
Advantage of ReactJS
Performance Enhancement
The biggest advantage of ReactJS is its efficiency and performance enhancement. The data flow that passes through the ReactJS application is very simple and easy to maintain. ReactJS enables you to manage your components, state, and props efficiently using an API called JSX which stands for “JavaScript XML”. This API has been designed to make it easier for developers who are new to ReactJS development and improve their efficiency during the development process.
ReactJS also provides an effective way of handling styling of your components with CSS properties like classes or ids which can be applied dynamically while building your application or even while testing it.
Easy to Learn and Use
ReactJS is easy to learn and use. The learning curve is quite shallow, especially compared to other JavaScript frameworks like Angular and Ember. There are plenty of resources online, including the official documentation, which is well-written and easy to follow.
ReactJS is also powerful. React makes it easy to build complex UIs without worrying about the complexity of managing browser rendering or handling events. You can focus on the business logic, not how your app will look on different browsers or platforms.
Reusable Components
ReactJS makes it easy to build components that are reusable across your site or application. This is done by reusing the same components over and over again, even if they’re not in use on any given page or screen.
For example: if you have a button that you want to use throughout your whole app, you can put it inside of a <Button> component, which will allow you to reuse it anywhere else in your app without having to create new versions of that component for each place where you want it used (e.g., different sizes of buttons).
The Support of Handy Tools
ReactJS has a lot of tools that make your life easier. The most important tool is the Babel transpiler, which compiles all your JavaScript code into a single language called JSX. This allows you to write all your code in JavaScript, but it also enables you to use React’s features such as JSX literals and virtual DOM manipulation, which are not available in plain JavaScript.
Another great tool that ReactJS provides is the state management library called Redux. Redux helps manage the application state by giving you two-way data binding between your components and actions. You can also use redux-thunk middleware to perform asynchronous actions asynchronously, which is very useful for performing server-side rendering (SSR).
Finally, React also provides a set of libraries called react-native which lets you develop mobile apps using native tools like Xcode or Android Studio while keeping them consistent with React patterns.
Scope for Testing the Codes
The scope for testing the codes is wider in ReactJS. A component can be tested at multiple levels. There are two main approaches to testing a component:
- Test the component’s behavior.
- Test the component’s state and props.
You can use Mocha or Chai to test your ReactJS codes. ReactJS enables you to create a component, add it to your parent component, and test it without any initial setup. This makes it perfect for unit testing and integration testing.
With ReactJS it’s very easy to debug your application because of its virtual DOM. You can use the developer tools to see how the application looks in real-time and also make changes to the code without breaking anything.
It’s also very fast when it comes to rendering new elements on the screen, which makes things faster so you don’t have to wait too long for things to work properly.
