Answer 1

This should work

function array_count_values(array) {
  var tmpArr = {};
  var key = '';
  var t = '';
  var _countValue = function(tmpArr, value) {
    if (typeof value === 'number') {
      if (Math.floor(value) !== value) {
        return;
      }
    } else if (typeof value !== 'string') {
      return;
    }
    if (value in tmpArr && tmpArr.hasOwnProperty(value)) {
      ++tmpArr[value];
    } else {
      tmpArr[value] = 1;
    }
  }

  for (key in array) {
    if (array.hasOwnProperty(key)) {
      _countValue.call(this, tmpArr, array[key]);
    }

  }

  return tmpArr;
}
console.log(array_count_values([12, 43, 12, 43, "null", "null"]));
