Can i write this condition in shorter version?
I want to get last index of array arrarr and if the array is emty, I want to get 00 (so basically add -1-1 to arr.lengtharr.length if arr.lengtharr.length is not 00)

const index = !!arr.length ? arr.length - 1 : 0;

const index = !!arr.length ? arr.length - 1 : 0;
