Description

I propose that the prefer-optional-chain rule should also check for !foo || !foo.bar the boolean alternative form of !(foo && foo.bar) to be suggested as !foo?.bar

Fail

!foo || !foo.bar;

!foo || !foo[bar];

!foo || !foo.bar || !foo.bar.baz || !foo.bar.baz();

Pass

!foo?.bar;

!foo?.[bar];

!foo?.bar?.baz?.();
