— Dont reinvent the whee!

Hey, I'm trying to decunstructure H = {h: 123, s: 123, v: 123} into h, s, v, but can't get it right.

— const { h, s, v } = H;

— Wait uhhh, let?

— But they are already created above?

— { h, s, v } = H;

— Try that

— Should work

—

function HSVtoRGB(H, S, V) {
  let r;
  let g;
  let b;
  const h = H;
  const s = S;
  const v = V;
  if (arguments.length === 1) {
    const { h, s, v } = H;
  }

— Noop, you can't const them if you're gonna modify them later

—

function convert(h, s, v) {
  // conversion logic
}

function HSVtoRGB(H, S, V) {
  return arguments.length === 1
    ? convert(H.h, H.s, H.v)
    : convert(H, S, V);
}

— This is how I would do it
