Count the number of files in a directory using JavaScript/nodejs?

Question

How can I count the number of files in a directory using nodejs with just plain JavaScript or packages? I want to do something like this:

How to count the number of files in a directory using Python

Or in bash script I'd do this:

getLength() {   DIRLENGTH=1   until [ ! -d "DIR-$((DIRLENGTH+1))"  ]; do     DIRLENGTH=$((DIRLENGTH+1))   done }

Using fs, I found retrieving the directory file count to be straightforward.

const fs = require('fs'); const dir = './directory';  fs.readdir(dir, (err, files) => {   console.log(files.length); });
