For instance:
var x = y = z = null;
var list = [x, y, z];
var number = 10;
Is there a way to assign number to x using list, without replacing list[0]?

Is it possible to assign a value to a variable stored in an array?
No, you cannot do that.
It's important to understand that in JavaScript, variables are passed by value, not by reference. This means that when you create an array like [a, b, c], the array does not hold references to the variables a, b, and c; instead, it holds the values that those variables had at the time the array was created.
So, once the array is created, it doesn't keep track of where those values came from. It treats them just like any other literal value or expression you might use to populate the array, such as [1, 40 + 2, "foo"]. Each value is evaluated and added to the array without any reference back to the original variable.
