Support for forEach

[haejunejung]

Hello, @raon0211!
If you need forEach, Can I work it?

If you don't mind working with it, in the case of forEach, it only applied to arrays, but I understand that compat(lodash) supports some objects. So, I plan to ensure that only compat support objects.

I guess this is necessary. Thanks for helping us!
