confirmTheEnding.js

function confirmEnding(str, target) {
  return str.substr(target.length) === target;
}
confirmEnding("sesame", "same");
// why does the code above return "FALSE"?
// I originally thought, since (-target.length = -4)
// that "does substr(-target.length) === target?" meant does 'same' = the last 4 characters of str? but (-4) is actually an index, so you start at -4th letter, which is 's' and you go to the end, which gives you "same".
