Typically, this main entry script can be found in the main.jsx file, located in the project’s src/ folder. This render() method, which is provided by the React library (to be precise, by the react-dom package), takes a snippet of JSX code and interprets and executes it for you.
The complete snippet you find in the root entry file (main.jsx) typically looks like this:
import React from 'react';
import ReactDOM from 'react-dom/client';
