Kotlin in Action: Chapter 8 Exercises

Chapter 8 covers higher order functions, which is just a fancy way of saying functions that can take a function as a parameter or return a function (or both). it also covers other points such as inline functions, non local returns, and many other such points.

Exercise: Filter Out

So for a simple exercise to test our knowledge out, let's create a method that takes in a lambda.

As usual, an answer will be given in a follow up post. And the answer can be found here.
