Hello everyone!
I’m having some problem with this function. Maybe I’m missing something… the test is pass 3/5 and for some reason when I compare if the first charAt is UpperCase is still returning true when is not supposed to be true))
Please give me some kind of hint :grinning:

Your code so far

function myReplace(str, before, after) {
  var re = /^[A-Z]/ig;
  
  return str.replace(before, function replacer(match){
    return !re.test(match.charAt(0)) ? after : after.charAt(0).toUpperCase() + after.substring(1);
  });
}


myReplace("Let us go to the store", "store", "mall");

Never mind)) I found my mistake. It had to do with Regex.
It supposed to be /^[A-Z]/ :grin:
