  • Another pro is that ReactJS is very easy to learn, especially if you already have experience with JavaScript.

However, there are also some cons to ReactJS development.

  • It can be difficult to debug ReactJS applications. This is because the code can get very complicated, particularly when you are using multiple components.
  • ReactJS only works with web browsers that support the HTML5 history API. This means that older browsers may not be able to run ReactJS applications.

Step-by-step ReactJS Development Process

  • The first step in ReactJS development is to create a new ReactJS project. This can be done using the create-react-app command line tool.
  • Once the project has been created, the next step is to install all of the dependencies that are needed for ReactJS development. The package.json file contains a list of these dependencies.
  • The following step is to design a new component. Components are the building blocks of ReactJS applications. They can be created using the create-Component() function.
  • Once the component has been created, it needs to be registered with the application. This can be done using the AppRegistry.registerComponent() function.
  • Finally, the component needs to be rendered to the DOM. This can be done using the ReactDOM.render() function.
