Node script to write filename and extension to filesystem based on an array of filenames. Helpful for creating a list of container files to copy and paste content into. My use case was taking an array of svg icon names to then have content dumped into them.

createBulkFileSimple.js

import fs from 'fs';

const folderUnderDirname = 'folder';
const fileExtension = '.html.twig';
const files = [
    'filename-goes-here',
];

files.forEach(async file => {
    await fs.promises.writeFile(`${__dirname}/${folderUnderDirname}/${file}${fileExtension}`, file, { flag: 'wx' });
});
