Check that value is object literal?

Question

I have a value and want to know if it\'s an iteratable object literal, before I iterate it.

How do I do that?

Answer 1

This works for me:

function isObject(o) {
    try {
        return ((typeof o == "object") && (o !== null) && (o.length === undefined));
    } catch (err) {
        return false;
    }
}
