Solution Review: Find the Minimum in an Array

let arr = [| 23, 45, 17, 10, 60, 54 |];
let findMin = (arr: array(int)) => {
  let min = ref(-1);
  
  min := arr[0]; /* Start with the first value of the array */
  for (i in 1 to Array.length(arr)-1) { /* Travrse the array */
    if (min^ > arr[i]) { /* Whenever a value smaller than min is found */
      min := arr[i]; /* Make it the new min */
    };
  };
  min^;
};
Js.log(findMin(arr));
