    Explanation for nerds

    The reason is the JS compiler removes whitespace and introduces semicolons only “where necessary”.

    So writing

    function myFn() {
  return true;
}

    Is not the same as

    function myFn() {
  return 
    true;
}

    Because the compiler will see that and make it:

    function myFn() { return; true; }

    You big ol’ nerd. Tee-hee.

      That’s terrifying, especially in JS where no type system will fuck you up for returning nothing when you should’ve returned a boolean.
