Shameless plug, I introduced an ECMA proposal for a conditional rest and spread operator a few months ago and would appreciate support or suggestions if you would find it useful.

Not sure about the proposed form, but having proper expression-only ifs in arrays and objects would be nice. Including the spread syntax.

  [
    "foo”,
    if (cond1) bar,
    if (cond2) ...baz,
  ]
Pretty sure it was already proposed and rejected, but still.

This ain’t pretty, but it works:

  [
    “foo”,
    ...(cond1 ? [bar] : []),
    ...(cond2 ? baz : []),
  ]

Nice one. I run into this regularly, and it always leads to some kind of nullish spread spaghetti. I really like the idea of an empty / non-value operator that works on objects, arguments & iterables.

Q - is it just a matter of liking posts on tc39 discourse to show support?
