JavaScript Pass Variables Through Reference

Question

Is there an equivalent in JavaScript for PHP\'s reference passing of variables?

[PHP]:

function addToEnd(&$theRefVar,$str)
{
    $theRefVar.=$str;
}
$myVar=\"H         


        

Answer 1

The other answers/comments describe the situation well enough, but I thought I'd offer and alternative if you need that style of functionality, by using a callback.

var someText = "asd";
addToEnd(someText, "fgh", function(val) { someText = val; });

and

function addToEnd(original, str, setValue)
{
    setValue(original += str);
}

but a better solution would be

var someText = "asd";
someText = addToEnd(someText, "fgh");

and

function addToEnd(original, str)
{
    return original += str;
}
