The various forms of
This topic isn’t a tremendously complicated, but it can be difficult because it is rather tedious. I remember it as a source of endless frustration when I was first learning Haskell: Why so many strings? Why do I have to waste my time looking up functions to convert between different representations(lazy, strict, builder)
of the same thing?
It turns out these types all exist for a reason, and once you understand these reasons, it should become clear why we actually do care about which type we’re using and when we convert between them.
