Number.NEGATIVE_INFINITY is a special value that returns when an arithmetic operation or function generates a number smaller than the smallest negative number that JavaScript can represent (that is, smaller than -Number.MAX_VALUE).

JavaScript displays NEGATIVE_INFINITY when using -InfinityThis value has an arithmetic behavior very similar to infinity. For example, any number multiplied by infinity results in infinity, and any number divided by infinity results in 0.
