async function listDirectories(rootPath) {

 const filePaths = fileNames.map(fileName =&gt; path.join(rootPath, fileName));

 const filePathsAndIsDirectoryFlags = await Promise.all(filePathsAndIsDirectoryFlagsPromises);
 return filePathsAndIsDirectoryFlags.filter(filePathAndIsDirectoryFlag =&gt; filePathAndIsDirectoryFlag.isDirectory)

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:

<pre><code>&lt;MyFolder&gt;
|- SomeFolder
|- SomeOtherFolder
|- SomeFile.txt
|- SomeOtherFile.txt
|- x-directory
</code></pre>

I would expect to get an array of:

<pre><code>["SomeFolder", "SomeOtherFolder", "x-directory"]
</code></pre>

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

So does anything already exist to do the above?
