Script Preparation code:

var arrays = Array.from({ length: 1000 }).map(() => new Array((Math.random() * 1000 | 0)).fill(0));
function min_one(arrays) {
  return Math.min(...arrays.map(arr => arr.length));
}
function min_two(arrays) {
  	var smallest = arrays[0].length;
	for (var i = 1; i < arrays.length; i++) {
      var arr_len = arrays[i].length;
      if (arr_len < smallest) smallest = arr_len;
	}
