JavaScript

Hi everyone. I want you to check my code please and tell me where is the wrong.

function myReplace(str, before, after) {

  if (/^[A-Z]/.test(before)){
    after = after.slice(0,1).toUpperCase() + after.slice(1)
  } 
  
  if(/^[A-Z]/.test(after)){
    before = before.slice(0,1).toUpperCase() + before.slice(1)
  }
  
  return str.replace(before, after)
}

console.log(myReplace("I think we should look up there", "up", "Down"))

What happens when you run it, what’s it supposed to do?

Is there an error?

Is there unexpected output?
