Randomness in functional programming
Randomness can be a tricky concept in functional programming. Functional programming principles emphasize pure functions, immutability, and referential transparency, meaning function should always return the same output for the same input. However, generating random values inherently violates this principle. Random numbers are by nature unpredictable and can change with every function call. In functional programming, the challenge is how to integrate randomness while keeping code clean and predictable. One approach is to separate the generation of random numbers from the core logic, treating randomness as an input or external effect. One elegant way to handle randomness in functional programming is by using a generator. Generators provide a controlled way to produce a sequence of values on demand, including random values. They allow you to encapsulate the side effect of generating random numbers while keeping the rest of your program pure. With generators, you can yield one random…
