• Searching in dependencies in package.json

React Version Using Command Line

We can use the below command to check the version of ReactJS. The below command shows the installed react version in our system.

React Version Using React.version Property

We can use the 'React.version' property to check the version of ReactJs installed in our system. The code mentioned below can be used to check the version of React using React.version property.

// file name - app.js
import React from "react";

const App = () => {
  return <h1> We are currently using {" "}{React.version} version of ReactJS </h1>;
};

export default App;

React Version Searching in package.json File

Apart from the two approaches mentioned above, we can simply search in our project's package.json folder to find the version of ReactJs we are using. Go to package.json file of the project then there will be a dependencies section, and the ReactJS version will be written there.
