Tell us what’s happening:

I’ve always struggled to create regex. I understand how it works, I’m amazed by what that can do, but I hate them.

Furthermore, I have this message error:

Your second new character class should match the digits 0 trrough 9

Technically, and please, correct me because I’m wrong, there is this second new character class that should match the digits between 0-9 no ? Should I have an /g at the end ?

Your code so far


const evalFormula = (x, cells) => {
  const idToText = id => cells.find(cell => cell.id === id).value;
  const rangeRegex = /([A-J])([1-9][0-9]?):([A-J])([1-9][0-9]?)/;
}

Hi @A.I

You are supposed to code the range in stages. You coded for the complete range. Only do as much as the instructions ask.

Happy coding
