The native method of JavaScript gets the maximum (minimum) value in an array _ basics

The simplest way to get the maximum (minimum) value in an array is to iterate through the arrays and find the maximum (minimum) value by comparison. But in fact, in the native method of JavaScript, there are some quick ways to implement this functionality.
1 Array.prototype.sort

Copy Code code as follows:

var a = [7,3,4,6,10];
A.sort (function (a,b) {
return (a-b);})

Note that the comparison function in sort must be passed in, and if this function is not passed, the result of A.sort () is [10,3,4,6,7];

2 Math.max,math.min

Copy Code code as follows:

var a = [7,3,4,6,10];
var max = Math.max.apply (math,a);
var min = Math.min.apply (math,a);
