    Hi,

    I have a statement like
    var a = {};

    Does that mean a is an object or an array?

    Also, later in the code I have something like
    a.name = "temp";
    a.age = 25;
    etc.,

    Now, how do I access a's variables dynamically? i.e a method like

    getDetails(fieldname){
    return ( a.eval(fieldname));
    }
    But eval() throws an error in IE.
    Any suggestions please.
    thanks.

    Yes, var a{}; is an object, you're declaring it using Object Literal notation.
    Check the wikipedia page for Object_literal.

    You seem to have answered your other question in a followup post.
