JS Get properties from many files at once

What I have: 50 mp3 files in a folder. What I want to do: Create an object for every file that includes name and src.

What I don't know how to do is select and get properties from all of the files. Is it even possible? I know that you can get info from a text file via JS.

It would maybe be something like:

for (var i = 0; i < musicFolder.length; i++) {
 var object = new Object (
 musicFolder[i].title,
 musicFolder[i].path/src
 );
 objectArray.push(object);
}

I would perhaps need to select an entire folder, but I dont know how to do this is JS.

Assuming that you are running this in Node.js and you only need the name and the path of the file, you can do this:

var fs = require('fs');
path = 'your path here';
const res = [];
fs.readdir(path, (err, items) => {
  for (var i=0; i<items.length; i++) {
    res.push({
      name: items[i],
      src: `${path}/${items[i]}`
    });


  }
  console.log(res)
});

This will iterate your folder and list all the files in it. Then it will save the name of the file and its path in a object and push it to an array.
