Array.some
var i = getNext(), tempResult = arr.some(v => v === arr[i]);
Array.filter
var i = getNext(), tempResult = !!arr.filter(v => v === arr[i]).length;
Array.indexOf
var i = getNext(), tempResult = arr.indexOf(arr[i]) !== -1;
Array.findIndex
var i = getNext(), tempResult = !!arr.findIndex(v => v === arr[i]) !== -1;
