Javascript. Assign array values to multiple variables? [duplicate]

Answer 1

It is possible only for Javascript 1.7 as already answered by @Justin. Here is a trial to simulate it in the widespread browsers:

function assign(arr, vars) {
    var x = {};
    var num = Math.min(arr.length, vars.length);
    for (var i = 0; i < num; ++i) {
        x[vars[i]] = arr[i];
    }
    return x;
}
var arr = [1, 2, 3];
var x = assign(arr, ['a', 'b', 'c']);
var z = x.a + x.b + x.c;  // z == 6

I don't know how useful it is.
