Synopsis

Now on to programming with Types, Things are getting pretty good. Creating types with and | or Semigroups Parameterized Types The Maybe type Start with some definitions Algebraic data types: a composite type, meaning, any types that can be made by combining other types. and / product types: combining two or more types, very common. nearly all languages have support for these. Structs in C. This can often be the only way to make new types. This is the basis for class hierarchies. abstracting out what they have similar, and move downward. “real life is full of extreme edge cases” Side note about data and declaring, or forming the data. I really thought FP was function driven. But I’m not so sure I’d say that today. Yes yes functions as values are super important, but they more enable us to really focus on the structure and transformation of data, instead of actions or events on that data. or / sum types: > In computer science, a tagged union, also called a variant, variant record, choice type, di
