Rust, Ruby, and the Art of Implicit Returns

The article explores the nuances of expression-based programming, particularly in languages like Rust, Ruby, Kotlin, and Scala, and how it contrasts with statement-based programming typically found in C-style languages. It emphasizes how implicit returns, if-expressions, and single-expression functions can enhance code readability and conciseness by eliminating redundant syntax, such as the return keyword. The discussion highlights the transition from explicit statements to expressions that return values, using examples from several programming languages to illustrate the shift. The author argues that embracing expressions simplifies code and improves its ergonomics, advocating for a thoughtful integration of these concepts to enhance clarity and maintainability. The piece ends by inviting readers to explore these languages to experience the elegance that expression-based programming can offer.
