I have a string variable which contains the name of an array. What I\'d like to do is access an element of that array. And write it to another variable. How can I do this?

    I mean you can use eval, but it is not the best approach:

    eval("var arrayname = sample");
    var number = arrayname[1];  
    

    Why not just do:

    var arrayname = sample;
    var number = arrayname[1];
