disallow comparing against -0 (no-compare-neg-zero)
The "extends": "eslint:recommended"
property in a configuration file enables this rule.
Rule Details
The rule should warn against code that tries to compare against -0, since that will not work as intended. That is, code like x === -0 will pass for both +0 and -0. The author probably intended Object.is(x, -0).
Examples of incorrect code for this rule:
if (x === -0) {
// doSomething()...
}
Examples of correct code for this rule:

Version
This rule was introduced in ESLint 3.17.0.
