}

function exerciseTwo(AnimalClass){
// Exercise Two: In this exercise you are given a class called AnimalClass.
// The class will already have the properties 'name', 'noise' on it.
// You will be adding a method to the prototype called 'speak'
// Using the 'this' keyword, speak should return the following string:
// '<name> says <noise>'

AnimalClass.prototype.speak = function()
{
this.speak = name + 'says'; noise;
return this.speak ;
};
