Currently, only struct on struct or interface on interface embedding is explained in OOP.md.

It would be nice to have an explanation about embedding interfaces into structs.

Here's a nice example:
https://github.com/dapr/components-contrib/blob/master/state/store.go#L51

In this example the DefaultBulkStore struct embeds the Store interface, DefaultBulkStore the uses the embedded Store interface to also implement BulkStore.

Here's a few things you may want to add:

1. A block discussing receiver pointers would be good, such as when to use them, the difference between using them and not, etc.
2. Function type definitions (example: https://play.golang.org/p/O3ImsRIXCO)
3. Factory methods such as func New(name string, age int) Person {...} and maybe how the factory pattern can be used with interfaces.

I personally have been recently favoring function type definitions and interfaces far more over struct methods, especially when your datasources may change. This is extremely helpful when writing unit tests because you can much create mock functions that adhere to your function type definitions or interfaces. Otherwise, you basically end up being forced to write special cases in your code or creating functional tests instead of unit tests.

Just my thoughts.

Just want to ask about the jmp-table in OOP.md,

Is it jmp-table or jump-table? Because I couldn't find anything with jmp table,

I googled it and found jmp is a software.
