Exercise 2 : Basic Number Filtering

How to write unit test cases.

• How to design small functions for specific use cases.

• Code reuse: reusing even and odd functions in Stories 4, 5 and 6, reusing various functions in stories 7 and 8.

• How to compose multiple functions together? How to form a chain of functions?

• Identify abstractions using higher order functions (functions that accept or return functions). i.e. using functions as first-class citizens.

• Understand Go’s generics and whether and how these can be used to write generic methods that can operate on any type.
