In JS, how can I use a string to define a JS object parameter?

Question

I have a function defined that way:

var myObject = new Object();

    function myFunction(someString){

         myObject.someString= 0;

    }

The problem is someString is taken as the string someString instead of the value of that variable.

So, after I use that function several times over with different someString's, I would like to get an object with all the values for each someString.

But when I loop through that object The only result I get is someString : 0

I want to get:

John : 0
James : 0
Alex : 0 etc....

How do I do that? Thanks a lot in advance

You can use the associative array approach:

var someString = 'asdf';

myObject[someString] = 0; // {asdf: 0}
myObject['foo'] = 'bar';

You can basically use any string to retrieve your method/parameter.

var i = 1;
myObject['test' + i] = i + 1; // gives us {test1: 2}

Try this

var myObject = new Object();
    function myFunction(someString){
        myObject[someString]= 0;
    }
