 # disallow negating the left operand in `in` expressions (no-negated-in-lhs)
 
+This rule was **deprecated** in ESLint v3.3.0 and replaced by the [no-unsafe-negation](no-unsafe-negation.md) rule.
+
 ## Rule Details
 
 Just as developers might type `-a + b` when they mean `-(a + b)` for the negative of a sum, they might type `!key in object` by mistake when they almost certainly mean `!(key in object)` to test that a key is not in an object.
