Prefer using a logical operator over a ternary

💼 This rule is enabled in the ✅ recommended config.

💡 This rule is manually fixable by editor suggestions.

Disallow ternary operators when simpler logical operator alternatives exist.

Ideally, most reported cases have an equivalent Logical OR(||) expression. The rule intentionally provides suggestions instead of auto-fixes, because in many cases, the nullish coalescing operator (??) should be preferred.

Fail

foo ? foo : bar;

foo.bar ? foo.bar : foo.baz

foo?.bar ? foo.bar : baz

!bar ? foo : bar;

Pass

foo ?? bar;

foo || bar;

foo ? bar : baz;

foo.bar ?? foo.baz

foo?.bar ?? baz
