Polyglot Data Modeling: Enums in TypeScript, Go, and Rust

Choosing the right data structures is essential for writing clean, type-safe, and efficient code. While many languages support enums, they handle them in radically different ways, from simple runtime objects to powerful algebraic data types. This text-only course guides you through the concepts of enums, pattern matching, and memory management across three major modern languages: TypeScript, Go, and Rust. By comparing these languages, you will develop a deep mental model of how data is represented in memory and how to design robust APIs. You will transition from basic type definitions to understanding advanced concepts like Rust ownership, self-referential types, and map references. What you'll learn: - Understand the fundamental role of enums and algebraic data types in modern software development. - Compare how TypeScript, Go, and Rust implement, compile, and optimize enums. - Analyze Rust-specific memory concepts including ownership, borrowing, and map references. - Explore self-referential data structures and learn how to handle them safely within type systems. - Apply pattern matching techniques to write robust, exhaustive, and error-free control flow. - Examine how macros and code generation simplify enum usage in systems programming. This course begins with foundational definitions of enums and basic type systems, then moves on to comparative language implementations, and finishes with advanced memory layout and reference handling. It is designed for beginner developers and programmers looking to expand their polyglot coding skills. No advanced systems programming experience is required.
