var calc = { sum : function(a, b) {
return a+b;
}
};
Now call it using:
var test = calc.sum(1,2);

the basic concept is
var calc = {};
calc.sum = function(a, b) {
return a+b;
}
As well you can do:
var createCalc = (function(){
var sum = function(a, b) {
return a+b;
};
return {
sum : sum
}
});
var cal = createCalc();
or
function Calc() {
this.sum = function(a, b) {
return a+b;
};
}
var calc = new Calc( );
I always recommend this github with patterns. http://shichuan.github.io/javascript-patterns/#object-creation-patterns

You can simply define the object like so:
var calc =
{
sum : function(a,b){ return a + b; }
};
Comments
var calc={
sum:function(1,b){
return a+b;
}
}
Now you can use this method
var value = calc.sum(1,3)
//value = 4
