Pear: Find the maximum and minimum values in an array

The common practice is to iterate through the array, compare, write out the code looked like pomegranate sister, although a beautiful woman, but always feel a little awkward, how to turn her into like Chou-Heung as graceful and charming? Do you remember Math.max?

var numbers = [5, 6, 2, 3, 7]; /*  */var max = Math.max.apply(null/*/var min = Math.min.apply (null, numbers);

What if the array is large? Cut it into a loop.

function Minofarray (arr) {  var min = Infinity;   var QUANTUM = 32768;    for (var i = 0, len = arr.length; i < len; i + = QUANTUM)    {var submin = Math.min.appl Y (null, Arr.slice (i, math.min (i + QUANTUM, Len)));     = math.min (submin, Min);  }   return min;} var min = Minofarray ([5, 6, 2, 3, 7]);
