Objective: Sum two numbers and print the result in the format “The answer is: X” where X is the sum of the two numbers:

Object-oriented masturbation solution:

function MathLib(){

this.answer = null;
}

MathLib.prototype.sum = function (x,y){

this.answer = x + y;
}

MathLib.prototype.getAnswer = function(){

return this.answer;
}

function Printer(){

this.preText = ”;
}

Printer.prototype.setPreText = function(str){

this.preText = str;
}

Printer.prototype.out = function (str){

document.write(this.preText + str);
}

// To run
var math = new MathLib();
var print = new Printer();
math.sum(1,1);
print.setPreText(‘The answer is: ‘);
print.out(math.answer);
