The famous slogan "Well-typed programs do not go wrong."

The "Statics" of a language define what it means for a program to be "well-formed" before it ever runs. You explore:

15-312 isn't just a class; it’s a shift in perspective. It turns programming from an art of "poking the machine until it works" into a rigorous discipline of . 15312 foundations of programming languages

You start thinking like a type checker. You begin to catch "impossible" bugs before you even hit compile because you've designed your data structures to be mathematically sound.

If you ever want to build your own DSL (Domain Specific Language) or contribute to a major compiler like LLVM or Rust, these foundations are non-negotiable. Recommended Resources The famous slogan "Well-typed programs do not go wrong

How a compiler can figure out what you mean without you telling it.

Once you understand the underlying types (sums, products, functions), every new language is just a different combination of the same fundamental building blocks. You start thinking like a type checker
