Iterate over an Array or an Object invoking a function for each item.

If `obj` is an Array callback will be called passing
the value, index, and complete array for each item.

If 'obj' is an Object callback will be called passing
the value, key, and complete object for each property.

@param {Object|Array} obj The object to iterate
@param {Function} fn The callback to invoke for each item
