Promise example does nt work

[mtt-artis]

the example code doesnt work on my machine

const fs = require('fs');

const fileNames = ['file1.csv', 'file2.csv', 'file3.csv'];
const fileIndex = 0;
const nextStreamAsync = () => {
  return new Promise((res) => {
    if (fileIndex === fileNames.length) {
      return null;
    }
    return fs.createReadStream(fileNames[fileIndex++]);
  });
};

const combinedStream = new StreamConcat(nextStreamAsync);

but this does

const fs = require('fs');

const fileNames = ['file1.csv', 'file2.csv', 'file3.csv'];

let fileIndex = 0;
const nextStreamAsync = () => {
  return new Promise((res) => {
    if (fileIndex === filesPath.length) {
      return res(null)
    }
    return res(fs.createReadStream(filesPath[fileIndex++]))
  });
};
const combinedStream = new StreamConcat(nextStreamAsync);

you should resolve the promise

@mtt-artis Apologies for the delay, thanks for the catch! Feel free to submit a PR with that change and I'll take a look.
