Forever Functional: Better Error Handling with Monads (Part 2)

This post elaborates on the practical uses of monads in JavaScript, focusing on the Maybe monad to handle null values and the Either monad for error handling. It illustrates how these monads can simplify code by providing declarative mechanisms to manage optional values and errors, eliminating the need for verbose if-statements. The post provides code examples for both monads and demonstrates a real-life application involving customer data retrieval. Additionally, it introduces the Try monad for exception handling and briefly touches on using promises in a monadic way.
