Positive Number to Negative Number in JavaScript?

Question

Basically, the reverse of abs. If I have:

if ($this.find(\'.pdxslide-activeSlide\').index() < slideNum - 1) {
  slideNum = -slideNum
}
console.log(slideNu         


        

Answer 1

It will convert negative array to positive or vice versa

function negateOrPositive(arr) {
    arr.map(res => -res)
};
