我正在制作一个不和谐的机器人，需要一些Powershell代码翻译成Javascript

$CurrentDirectory = Get-Location

var currentDirectory = process.cwd();

New-Item -ItemType Directory -Path "C:\NewFolder"

const fs = require('fs');
fs.mkdirSync('C:/NewFolder');

Copy-Item -Path "C:\SourceFile.txt" -Destination "C:\DestinationFolder"

const fs = require('fs');
fs.copyFileSync('C:/SourceFile.txt', 'C:/DestinationFolder/SourceFile.txt');

Invoke-Expression -Command "ping google.com"

const { exec } = require('child_process');
exec('ping google.com', (error, stdout, stderr) => {
  if (error) {
    console.error(`执行命令出错: ${error}`);
    return;
  }
  console.log(`命令输出: ${stdout}`);
});
