My golang training repository
A collection of all my different training exercises from day 1.
About
Most of the exercises should be documented in the code telling what the code is for and how it work. But a few might be added a little bit to hasty, and lack good documentation.
TODO
Check that all projects are well documented.

20-functionChainingByReturningInterface
Same as test nr 19 for testing chaining functions on a struct, but this one returns an interface from the methods instead of a pointer to the structs, so we only make the methods available and not the types of the structs while chaining.
