This is the most critical theorem in the course. You will prove that a language is "safe" by proving two properties:

Whether you are a student at CMU or a self-taught developer diving into PFPL, mastering the foundations of programming languages is the ultimate "level up" for any serious programmer. AI responses may include mistakes. Learn more 15312 foundations of programming languages

15-312: Foundations of Programming Languages (FPL) at Carnegie Mellon University is more than just a coding course; it is a deep dive into the mathematical soul of software. While many computer science courses focus on to use a language, 15-312 asks a more fundamental question: This is the most critical theorem in the course

When a student writes a function in 15-312 that takes an input of type $A$ and returns an output of type $B$, they are effectively proving the logical implication $A \implies B$. The act of writing a function that type-checks is the act of constructing a valid mathematical proof. Learn more ### inferType 15-312: Foundations of Programming
