Here is one answer:

var numbers2 = [1, 4, 3, 7, 17, 267,267, 387,12, 12, 35];
var result;

function max(arr) {
  for (var i = 0; i < arr.length-1; i++) {
    if (arr[i] > arr[i + 1]){
        result = arr[i];
    } else if (arr[i] > arr[i + 1]) {
      result = arr[i];

    } else {
        /*do nothing, and counter will go up (this will deal with equal values) */
    }
    }

    console.log("i is : " + i);
    console.log("Result is " + result);

  return result;
}
console.log(max(numbers2));

alternatively there is a function Math.max that you could use: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/max

Thanks, sooooo much, I understand now. I'm still in the process of learning so didn't want to use the math function.
