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:

::: incorrect

/* eslint no-compare-neg-zero: "error" */

if (x === -0) {
    // doSomething()...
}
