here is that code cleaner version of it:

function toScreamingSnakeCase(variableName) {
  const lx = /[a-z]/
  const ux = /[A-Z]/

  let ssc = ''

  for(let c in variableName) {
    if(lx.test(variableName[c])) {
      ssc += variableName[c].toUpperCase()
    } else if (ux.test(variableName[c])) {
      ssc += (c == 0 ? '' : '_') + variableName[c]
    }
  }

  console.log(ssc, "!!", variableName)
  return ssc
}

toScreamingSnakeCase("user_id") // it passes even though it expects "USER_ID" but gets "USERID"  as a return value!!

you’re right i should have included reproducible code for it earlier, thanks for bringing that up, much appreciated.

happy coding :slight_smile:
