JavaScript's native method to obtain the maximum (minimum) value in an array_Basic knowledge

The simplest way to get the maximum (minimum) value in an array is to traverse the array and find its maximum (minimum) value through comparison. But in fact, some shortcut methods have been provided in the native methods of javascript to achieve this function.
1 Array.prototype.sort

Copy code The code is 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. If this function is not passed, the result of a.sort() is [10,3,4,6,7];

2 Math.max,Math.min

Copy code The code is as follows:

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