They didnt click with me, so it was very very hard, so much worse than 216 for me (unlike what the other commentators seem to be saying) Harder projects, easier/fairer tests. You'll cover a lot of different programming languages - Ruby, OCaml, and Rust. CMSC 330 Spring 2021 Static type checking Dynamic type checking More work for programmer (at first) Catches more (and subtle) errors at compile time Precludes some correct programs More efficient code (fewer run-time checks) Less work for programmer (at first) Delays some errors to run time
