bookdevelopmentNov 20, 2016, 6:33 AM UTCScala Functional Design & Programming - Chapter 6 (6)I've finished reading Chapter 6 of Scala Functional Design & Programming. This chapter explains how to handle state and tackles issues such as random number generation and state transitions. By introducing the Rand type and State type, and generalizing map, map2, and flatMap, we can smoothly handle state transitions. Finally, we experienced powerful stateless descriptions through a vending machine simulation.

bookdevelopmentOct 10, 2016, 1:15 AM UTCScala Functional Design & Programming - Chapter 5 (5)I read Chapter 5 of Scala Functional Design & Programming and learned about lazy evaluation and Stream implementation. Stream utilizes lazy evaluation to achieve efficient processing, and I learned about generating infinite streams and implementing functions using foldRight. After grasping the basics of Stream, I learned about generating infinite streams and implementing functions using unfold. Finally, I learned about implementing tails and scanRight.

First, I'll introduce the necessary credit cards and point sites to earn ANA miles, and explain how to achieve a 1.5-1.7% return rate through daily credit card use. It's also essential to utilize point sites efficiently to convert points to ANA miles.
bookdevelopmentSep 25, 2016, 12:38 AM UTCScala Functional Design & Programming - Chapter 4 (4)In Chapter 4 of Scala Functional Design & Programming, we learn about error handling. We discuss the problems with exceptions, and introduce the Option and Either types. By using these types, we learn how to handle errors in a type-safe manner. Specifically, we implement map, flatMap, and other methods for Option and Either, and learn practical error handling techniques.
