Haskell Programming from First Principles

• I’ve been interested in Haskell and other Functional Programming Languages for a while, so I decided to learn them.

• Setting up the environment seems troublesome on m1, so for now I’ll write code on repl.it.

• Referential Transparency

• Does this mean that if statements and variable declarations are all functions?

  • Interesting (blu3mo)

• It’s like type classes and protocols in Swift.

  • Haskell’s Eq is similar to Swift’s Equatable.

Impressions

• It feels very “mathematical”.
  • Not so much mathematics itself, but more like a “mathematical” language for handling numbers created by mathematicians(?)
    • I don’t really understand the way it is expressed.
    • The mechanisms (Lazy Evaluation, Referential Transparency) and the syntax (list comprehensions) as well.
• It’s fresh and very interesting.
  • It feels like it’s clearing the fog in the programming language world(?).
