All the file functions in Node.js are provided by the fs module. This module exposes a method called statSync(), which gets the file details synchronously.

When you call it and pass a file path (relative to the current location or absolute), it returns an object that contains the mtime property.

That is a Date object instance that contains the file last modified date.

const fs = require('fs')

const getFileUpdatedDate = (path) => {
  const stats = fs.statSync(path)
  return stats.mtime
}

See the JavaScript Date guide for more on working with the Date object.
