Get file names in a directory

Examples

Normal usage:

const filesInDir = require('files-in-dir');
const fileNames = filesInDir('/home/fred/Desktop');
console.log(fileNames);
// ['image_1.jpg', 'resume.pdf', 'why_worry.PNG'...]

Require specific extension(s):

const allowdExtensions = ['jpg', 'png']; // case insensitive
const someFileNames = filesInDir('/home/fred/Desktop', allowdExtensions);
console.log(someFileNames);
// ['image_1.jpg', 'why_worry.PNG'...]
