Is there an idiomatic way to write the conditional operator when you want nothing to happen in one case?

Question

For example, in the following I want to yield a value only if foo is truthy.

Syntactically I must include the second half of the conditional operator (the :), so is it idiomatic to put undefined here?

foo ? yield 'something' : undefined;

Why not use `&&` operator instead of ternary? – hindmost Jul 06 '17 at 16:21 — hindmost, Jul 06 '17 at 16:21
what's wrong with the old `if`? – Fabio Antunes Jul 06 '17 at 16:22 — Fabio Antunes, Jul 06 '17 at 16:22
Both good ideas I suppose. – Ben Aston Jul 06 '17 at 16:23 — Ben Aston, Jul 06 '17 at 16:23

No. You can't.

If you do not want to happen nothing just go with simple if.

if(foo)
 yield 'something'
