Interfaces 101 : Interface Type Assertion
Episode 6! - Watch and learn how you can use type assertions to write simple, yet effective, code. -- In this video, Miki will write a versatile logging library with Go interfaces.The first prototype he proposes consists of a type with an `io.Writer` interface field to handle writing data for the logger. Upon completing the first design, Miki realizes his type is missing a `Sync` function, which will enable developers to move data into stable storage while logging. To meet this requirement, Miki will create a new interface type with a `Sync` function.
Things you will learn in this video :
How to properly perform a type assertion on an interface.
How to move data from memory to stable storage.
Tips on designing an interface in Go.

Do you agree with the Go proverb : “the bigger the interface the weaker the abstraction”?
