  This is exactly how you need to write. But the function must return a value.
  
  In this case, function is the conditional name of the function. Since this is a function word, you cannot use it for naming.
  
  Show the function itself.

  ...
  
  if you write let abc = function (arg), then abc equals undefined

  
  
  Try it
  
  

  let abc = /* please give me a string */ function(arg)

  
  
  If it doesn't work, then only 3 options are possible:
  
  1. Most likely: this is a language bug, you have to accept and never use these buggy lines and functions.
  
  2. The function is asynchronous. The function returns a string sometime later.
  
  3. The function does not return a string. But wait, this can't be!
