Question about reversing string

1

Why does “return str” come before these other commands? Doesnt the function stop running after return is reached making it return the original str inputed? Also why are there no “;” in between the commands?

function reverseString(str) {
  return str
    .split("")
    .reverse()
    .join("");
}

Thanks.

Well, its spread across a bunch of lines. Here it is written a bit differently

function reverseString(str) {
  return str.split("").reverse().join("");
}
