Get all directories within directory nodejs

I was hoping this would be a simple thing, but I cannot find anything out there to do so.

I just want to get all folders/directories within a given folder/directory.

So for example:

<MyFolder>
|- SomeFolder
|- SomeOtherFolder
|- SomeFile.txt
|- SomeOtherFile.txt
|- x-directory

I would expect to get an array of:

["SomeFolder", "SomeOtherFolder", "x-directory"]

Or the above with the path if that was how it was served...

So does anything already exist to do the above?

Promise

const { promises: { readdir } } = require('fs')

const getDirectories = async source =>
  (await readdir(source, { withFileTypes: true }))
    .filter(dirent => dirent.isDirectory())
    .map(dirent => dirent.name)

Callback

const { readdir } = require('fs')

const getDirectories = (source, callback) =>
  readdir(source, { withFileTypes: true }, (err, files) => {
    if (err) {
      callback(err)
    } else {
      callback(
        files
          .filter(dirent => dirent.isDirectory())
          .map(dirent => dirent.name)
      )
    }
  })

Syncronous return

const { readdirSync } = require('fs')

const getDirectories = source =>
  readdirSync(source, { withFileTypes: true })
    .filter(dirent => dirent.isDirectory())
    .map(dirent => dirent.name)

List directories using a path.

function getDirectories(path) {
  return fs.readdirSync(path).filter(function (file) {
    return fs.statSync(path+'/'+file).isDirectory();
  });
}
