Javascript Return More Than One Range From Array.from() Method

Very new to Javascript, as I'm primarily using it to execute commands in Selenium IDE. I've been using the range function provided by Mozilla's documentation for the array.from() method. This is how I put it together in Selenium:

const range = (start,stop,step) =>
  Array.from(
    { length: (stop - start) / step + 1},
    (_, i) => start + (i * step)
  );
  return(range(179,199,1))

Is there a way to return more than one range? Why doesn't this work? (In Selenium IDE, it completely skips over this command.) Is it because it's a multi-dimensional array?

const range = (start,stop,step) =>
  Array.from(
    { length: (stop - start) / step + 1},
    (_, i) => start + (i * step)
  );
  return (range(179,199,1), range(201,210,1))
