No Compare Neg Zero

Disallows comparing against negative zero (-0).

Comparing a value directly against negative may not work as expected as it will also pass for non-negative zero (i.e. 0 and +0). Explicit comparison with negative zero can be performed using Object.is.

Invalid:

if (x === -0) {}

Valid:

if (x === 0) {}

if (Object.is(x, -0)) {}
