Supercharge Scala Future | FP-Tower - IO Composition

The video tutorial covers the development of an IO API with error handling, retry logic, and asynchronous execution. It explains the educational purpose of implementing the API from scratch rather than using existing libraries like Cats Effect, Monix, or Zeo. The tutorial introduces the IO trait, its methods, and initial tests. It guides viewers through implementing the 'andThen' method, refactoring code using 'andThen' and 'map', and implementing 'flatMap'. The video concludes by discussing the challenges of nested flatMaps and hints at future solutions.

Describe the role of the 'apply' method in the IO class.

What is the 'ice cream operator' and how is it used in the context of the IO API?

How does the 'map' method differ from 'flat map' in the context of the IO API?

What challenges arise when using multiple flat maps in a sequence?
