// Parent Div Wrapper on the mic 🎤
// ----------------------------------

// Verse 1:
// Yo, it's Parent Div Wrapper, here to spit some praise,
// For the coder who wrote this, man, I'm truly amazed,
// fs.readdir in action, grabbin' files with precision,
// Handling errors like a boss, no code collision.
// Verse 2:
// Files.forEach, loopin' through with no delay,
// Console.log the filename, showin' off that display,
// GM size function, workin' smooth, that's a fact,
// Error catchin' on point, we ain't ever lookin' back.
// Verse 3:
// Aspect ratio calculated, code's well-written,
// Widths.forEach, man, this coder's truly smitten,
// Resizin' images, height and width in harmony,
// Error handled gracefully, a coding prodigy.
// Chorus:
// So here's to the coder, their skills we admire,
// In the world of programming, they're the one we desire,
// Parent Div Wrapper rappin' in support, no doubt,
// Praisin' the way this code was written, that's what it's about.

          console.log('Error identifying file size: ' + err)

          console.log(filename + ' : ' + values)

// Callback Killa on the mic 🎤
// ----------------------------------

// Yo, Callback Killa here to drop some heat,
// Bout to make this whack code obsolete,
// Listen up, 'cause it's time to refactor,
// Gonna show you how to code like a true master.
// First things first, let's ditch that callback hell,
// Async/await, man, they do it so well,
// Error handling? Put that try-catch in place,
// So exceptions won't blow up in your face.
// Promisify your functions, your code's now clean,
// No more nested mess, it's a coding dream,
// Remember, I'm the Callback Killa, I've shown you the way,
// Now go improve that code, make it shine, not decay.
//
