how to use the lchownsync function from fs-extra in javascript

lchownsync function from fs-extra in JavaScript can be used to synchronously change the owner and group of a file with a specified file descriptor.

Here's how to use it:

const fse = require('fs-extra')

// Set owner and group of a file
const fd = 123 // replace with your file descriptor
const uid = 1000 // replace with your UID
const gid = 1000 // replace with your GID

try {
  fse.lchownSync(fd, uid, gid)
  console.log('Owner and group changed successfully.')
} catch (err) {
  console.error(err)
}

Make sure to replace the fd, uid, and gid with your own values. If the operation is successful, it will log a message to the console. Otherwise, it will log an error.

Note that lchownsync is a synchronous function, which means that it will block the execution of the rest of your code until the operation is completed. It's recommended to use the asynchronous version of this function (lchown) if you're working with a large number of files or performing this operation frequently.
