Ditching try...catch and null checks with Rust

A JavaScript developer transitioning to Rust explores the advantages of Rust's functional programming paradigm, particularly its approach to error and null handling, which contrasts with JavaScript's reliance on try...catch blocks. The post highlights Rust's use of the Result enum and pattern matching, which obligates developers to handle errors explicitly, thereby reducing the unpredictability often associated with JavaScript's error handling. Rust's absence of null values in favor of the Option type also promotes type safety by compelling developers to address cases where a value might be absent. The author argues that these features mitigate the anxiety of unhandled exceptions and improve code reliability, offering a safer and more predictable environment for managing errors compared to traditional object-oriented languages.
