Understanding Values, References, and Mutation: TypeScript, Go, and Rust

Every programming language handles data differently under the hood, and misunderstanding how variables are passed, copied, or mutated leads to hard-to-find bugs. This text-based course demystifies memory behavior by comparing three distinct paradigms: TypeScript, Go, and Rust. You will transition from writing code by trial-and-error to confidently predicting how your data behaves in memory, whether you are managing garbage-collected references or working with systems-level borrow checkers. What you'll learn: - Understand the foundational differences between value types and reference types in modern programming. - Analyze how TypeScript manages object references, memory allocation, and immutability patterns. - Master Go's pointer mechanics, understanding when to pass by value versus passing by pointer. - Explore Rust's unique ownership model, focusing on references, borrowing, and safe mutation rules. - Compare how different languages handle memory allocation on the stack versus the heap. - Debug common mutation errors and side effects by recognizing how data flows through your applications. You will start with core definitions of memory and variables, then progress through comparative written guides and code analysis for TypeScript, Go, and Rust. This course is designed for early-career developers and self-taught programmers who want to deepen their understanding of computer memory and write more predictable code, with no prior systems programming experience required. Start reading today to write safer, more efficient code across any language.
