Intermediate Algorithm Scripting - Spinal Tap Case

JavaScript

I need help with this regex please.
I dont understand how spaces are being put into the string with the first .replace(). To me it just says lower case alphabet then uppercase, but I cant see the space which is being inserted anywhere.

Your code so far

function spinalCase(str) {
  // Create a variable for the white space and underscores.
  var regex = /\s+|_+/g;

  // Replace low-upper case to low-space-uppercase
  str = str.replace(/([a-z])([A-Z])/g, "$1 $2");

  // Replace space and underscore with -
  return str.replace(regex, "-").toLowerCase();
}

// test here
spinalCase("This Is Spinal Tap");
