Javascript: Passing arguments from multiple functions to 1 function

I have several functions that evaluate some variables and come up with a result

For example:

function first(){
   //variable declarations
   var result1 = a+b
}

function two(){
   //variable declarations
   var result2 =c+d 
}

I want to pass both of those results to another function

function three( result1, result2 ) {
   var finalResult = result1 + result2;
}

My question is where do I call function 3 from. because in reality I have about 10 functions with results I need to pass. Do I put three(result#) at the end of each???

thankyou

A better way is to pass an object. It will make sure if you want to put more details, you wont have to add more arguments in the function and make it more readable.

function first(){
    return "value of one";
} 

function second(){
    return "value of two";
}


function three(data){
    var finalResult = data.first + data.second;
}

ANd call it like:

var data = {};
data.first = first();
data.second = second();

three(data);

Don't bother with the global results, i.e. result1,result2 etc. Just return the data and call 3 when ready with all

function first(){
 return a+b;
} 

function two(){
  return c+d;
}

function three(){
     return (first() + two());
 }

function one( a, b ) {
   var result1 = a + b;
   return result1;
}

function two( c, d ) {
   var result2 = c + d;
   return result2;
}

function three( a, b ) {
   var finalResult = a + b;
   return finalResult;
}

To call it use three( one(), two() );

Here is one approach you could take, although the question is a little vague.

function first(){
 return a+b;
} 

function two(){
 return c+d;
}

function three(){
 var finalResult = first() + two();
}

Or, if you didn't want the value in a function, you could do this:

<script>
 var results = first() + two();
</script>

function first() {
    return a + b;
}

function two() {
    return c + d;
}

function three(result1, result2) {
    return result1 + result2;
}

Call it:

var finalResult = three(first(), two());
