Struggling with Spinal Case Algorithmic Challenge

Tell us what’s happening:
Hi. I’ve been working on this challenge for a while now. I had some trouble learning regular expressions so had to look for other online tutorials. I think I’m finally getting it, and this challenge seems like it should be done, but two of the tests are still coming back with errors. I can’t seem to figure out why. Can anyone help here? Thanks.

  **Your code so far**


function spinalCase(str) {
let regex = /\s+|_+/g;
let newStr = str.replace(regex, '-');
newStr = newStr.replace(/([a-z])([A-Z])/g, "$1 $2");
newStr = newStr.toLowerCase();
console.log(newStr);
return newStr;
}

spinalCase('This Is Spinal Tap');

Try swapping the order of your two replace statements.

newStr.replace(/([a-z])([A-Z])/g, "$1 $2");

Is introducing spaces into the string after you have replaced spaces with “-”.
