create react app does not clear the terminal after start

When running yarn start or npm start to start the project created by create-react-app, the terminal will be cleared. When we are debugging, we often need to output some information in webpack. But it is cleared after start.

Solution:
find node_modules/react-dev-utils/clearConsole.jsthe file

'use strict';

function clearConsole() {
    
    
  if (process.env.REACT_APP_NO_CLEAR_CONSOLE) {
    
    
    return;
  }
  process.stdout.write(
    process.platform === 'win32' ? '\x1B[2J\x1B[0f' : '\x1B[2J\x1B[3J\x1B[H'
  );
}

module.exports = clearConsole;

After modifying the package.jsonfile REACT_APP_NO_CLEAR_CONSOLE add variables to the script command

  "scripts": {
    
    
    "start": "REACT_APP_NO_CLEAR_CONSOLE=true node scripts/start.js",
  },

It will not be cleared when you use yarn start again.
