whats wrong with this funtion?

[javascriptnewbie]

var sam=new Object();
sam.color=”red”;
sam.height= function(a+b){
return a+b;
}
document.write(sam.height(10,11));

Please.

you can’t use + in the function parameter list. you need to use a comma , to separate them.

var sam=new Object();
sam.color="red";
sam.height= function( a,b ){
    return a+b;
}

function Mph(miles, hours){
  this.miles = miles;
  this.hours = hours;
  this.milesPerHour = milesPerHour;
}

function milesPerHour(){
  return this.miles / this.hours;
}

var car1 = new Mph(100, 2);
alert(car1.milesPerHour()); // 50

Another way of doing it.
