Sinopsis

Corrections and feedback WOW, didn’t even mention immutability last week. When? at any point? Ever! Several of the examples we went over would have benefited from a mention that variables in Haskell are IMMUTABLE I put it in bold to make up for the lack of it last week. Maybe? Right? Also missed spoke about partial application. I said once the function gets all of it’s arguments, then and only then will it evaluate and return. But in Haskell that is not the case. If fact, it’s the exact opposite! Haskell is lazily evaluated so until that return value is needed, Haskell won’t do anything with it. Say like an infinity list, that is totally ok in Haskell, it’s not going to cause a stack overflow, or throw an exception. —we’ll get more into that later. Lists This is a big one. So much of the data structure and transforming is using lists! So we’ve got to get a really good understanding of this if we want to move forward and not fall on our faces. And by faces, I mean get over that hump and really understand Ha
