I’m having massive trouble with this one. I’ve tried using the “Get Hint” button and the codes never helped me. I’m so confused right now.

Your code so far

function spinalCase(str) {
  // "It's such a fine line between stupid, and clever."
  // --David St. Hubbins
  return str;

spinalCase('This Is Spinal Tap');
