Replace NULL with OPTION

Replace NULL with OPTION

In this video, we'll look at a functional programming construct called the option type, which helps avoid some common pitfalls in traditional programming, especially related to null values. Note, some languages, like Haskell, call this the maybe type. Null is a common tool in many programming languages used to signify the absence of a value. However, its simplicity is deceptive. Null usage often leads to several problems. Null reference exceptions are a frequent source of runtime errors that can lead to application crashes. Excessive null checks clutter code, complicating maintenance and readability. The term null can sometimes ambiguously represent different things depending on the context in programming. Often it is used to indicate the absence of a value, which can be interpreted in various ways such as unknown, not applicable, irrelevant, or simply as the default state indicating that something hasn't been initialized or doesn't exist. The option type represents a safer, more…
