: Formal study of functional, imperative, concurrent, and object-oriented programming models.

When you understand type safety, you understand why a compiler rejecting your code is a feature . Languages with strong foundations (Rust, Haskell, OCaml) allow you to change 50% of your codebase, and if it compiles, it likely works.

: Proving that "well-typed programs do not go wrong" using the properties of preservation and progress. 15312 foundations of programming languages

The curriculum evolves from basic structural concepts to advanced language features: 15-312: Foundations of Programming Languages (Fall 2023)

Studying 15312 is not merely an academic exercise. It offers practical advantages to software engineers: : Formal study of functional, imperative, concurrent, and

The structural representation of the code, typically modeled as an Abstract Syntax Tree (AST). 15-312 focuses heavily on abstract syntax to avoid getting bogged down by superficial stylistic choices. Static vs. Dynamic Semantics

Analyzes dynamically typed languages (like JavaScript or Python) as a special, single-typed subset of static languages. The Practical Value of Programming Language Theory : Proving that "well-typed programs do not go

Capturing the remaining execution path of a program, allowing the implementation of custom control flows like exceptions and coroutines.

Rules specify exactly how an expression transitions into a value, step-by-step.
