To compare the size of two numbers, the method encapsulates:
var i=4;
var j=5;
var rs=compare (I,J);
Console.info (RS);


2. The format definition of a method
/**
* Compare the size of 2 parameters
* @param first value
* @param the second value of second
*/
function Compare (first, second) {
if (First > second) {
return first;
} else {//First<=second
return second;
//        }
//    }

/**
* Addition operation
**/
var m=1;
var n=2;
var result=sum (m,n);
Console.info (Result)
//
function sum (m,n) {
var curresult=m+n;
return curresult;
//}
var a=2;
var b=3;
var rs=sum (A, b);
Console.info (RS);
function sum (first,second) {
return first+second;
//    }

Division operation

function divID (first, second) {
return first/second;
//    }
var c = 3;
var d = 6;
Console.info (divID (c, D));

Subtraction operations
var e=5;
var f=5;
var rs=minus (e,f);
Console.info (RS);
function minus (First,second) {
if (First>=second) {
return first-second;
}else{
return second-first;
}
}

/**
* Multiplication operation
**/
var g = 20;
var h = 3;
var rs = multi (g, h);
Alert (RS);
function multi (first,second) {
    Return First*second
}
