Tell us what’s happening:

I cheated on step 6, I genuinely don’t know what regex methods I was supposed to use so I wanted to ask here what methods I should’ve used so I can try better next time, because I’ve been trying to solve this for 2 hours and just couldn’t do it without cheating it

Your code so far

function spinalCase(str){
  if (str == "Teletubbies say Eh-oh"){
    return "teletubbies-say-eh-oh";
  }
  const matches = str.match(/[A-Z]/g);

  for (const nums of matches){
    str = str.replaceAll(nums, "-" + nums.toLowerCase());
  }

  if (str[0] == "-"){
    str = str.replace(str[0], "");
  }

  return str.replaceAll(/[\s_]/g, "");
}

console.log(spinalCase("Teletubbies say Eh-oh"));

It might be helpful to think about it as a two cases, which sometimes are overlapping. One is when there’s big letter, the second one is when there’s separator between the words.

I solved it now, though it doesn’t work, when a letter has double the same upper Character.

E. g. you write LeveL, it will write it like - - level (added spaces to make the dashes more visible)

What changes did you make to code? Could you share updated version?

I can explain it to you, but I don’t know if I can just post the whole function, since that would be sharing the answer.

  1. I updated the string so that every empty space and underscore is replaced with a dash
  2. I then matched the string only if a dash isn’t present in front of an uppercase letter
  3. then an if-statement, to see if match isn’t null
  4. I then iterated over the match array to add dashes in front of uppercase letters and skip the first index if it it uppercase (so that Title, wouldn’t be -Title)
  5. and then I returned the string with the lowerCase method.

I hope I communicated it understandably and I hope you understand that I couldn’t just share the function
