JS method to obtain the maximum value, minimum value and length of an array_javascript skills

The example in this article describes the JS method of obtaining the maximum value, minimum value and length of an array. Share it with everyone for your reference, the details are as follows:

//最小值
Array.prototype.min = function() {
var min = this[0];
var len = this.length;
for (var i = 1; i < len; i++){
if (this[i] < min){
min = this[i];
}
}
return min;
}
//最大值
Array.prototype.max = function() {
var max = this[0];
var len = this.length;
for (var i = 1; i < len; i++){
if (this[i] > max) {
max = this[i];
}
}
return max;
}
//数组长度
var array = new array(1,2,3,2,4,55,2);
alert(array.length);//输出7
