JavaScript adds more methods to arrays by prototyping

First, the method of getting the maximum value of the array

vararr = ["NBA", "haha", "CBA", "AAA", "SBC"]; Array.prototype.getMax=function() {vartemp = 0;  for(varX=1; x< This. length; X + +) {if( This[x]> This[temp]) {Temp=x; }}return  This[temp]; } alert (Arr.getmax ());//all of this represents the arr array, and that object calls this method this means who

Second, the string representation of the array, defines the ToString method. Equivalent to a replication in Java.

function () {    return "[" +this. Join ("/") + "]";} var arr=[32,23,32,34322,3232,2453];alert (arr.tostring ());
