From Python and C and Haskell, to Java and Rust and Pascal, to Fortran and Perl and APL, …from declarative and functional, to imperative and intentional, to object-oriented and procedural, …from analyzing and parsing, to syntax and compiling, to semantics and typing, we'll talk about it all. This class is a whirlwind tour of programming languages, their history, how they work, and how they differ from each other.
