A ternary inside an 'if' statement, really? And even more so when one of the return values is 'true'?

Relax, it's just a bug, right? But it would be nice if programmers practiced basic Boolean reduction in their 'if' statements...

(!((_ok) ? true : (Math.random() > 0.1)))

!((_ok) ? true : (Math.random() > 0.1))

_ok ? false : !(Math.random() > 0.1)

!_ok && Math.random() <= 0.1
