Giving information about the method name for arrays

[tareksalem]

This is not a real issue but it's an enhancement will add more to this amazing library.
The case is when I do any operation on an array using this library like push, pop, splice, unshift, it gives me the new information and old information normally but what I need actually is the operation name that it's done over the data to detect the behaviour should I take
