Javascript: passing multiple arguments as a single variable

Question

is it possible to pass multiple arguments using a single variable? For example, if I wanted to do something like:

function foo(x,y){
    document.write("X is " + x);
    document.write("Y is " + y);
}

var bar = "0,10";
foo(bar);

The example above is an simplified example of what I was trying to do. It doesn't work (because the "bar" is detected as a single argument). I know that there are easier ways to implement this using arrays.

So, I ask this question mostly out of curiosity - is it possible to get the "bar" variable to be detected as not one, but 2 arguments?

Thanks!

Answer 1

function foo(thing) {
    document.write("X is " + thing.x);
    document.write("Y is " + thing.y);
}

var bar = {x:0, y:10};
foo(bar);
