Error handling in JavaScript and TypeScript is notoriously challenging. Unlike many modern statically-typed languages (Rust, Swift, Kotlin, Go), TypeScript lacks built-in ways to track error types, often leading to fragile, opaque error-handling code. Although third-party Result type implementations have emerged to fill this gap, none have gained widespread adoption—mainly due to cumbersome syntax, complicated interactions with existing error-handling patterns, and unintuitive APIs.
In his latest blog post, Ethan Resnick explores these challenges, critically assesses current solutions, and proposes an improved Result type designed specifically for TypeScript. By aligning closely with the familiar Promise API, reducing boilerplate, and seamlessly integrating with async workflows, Ethan offers a practical, incremental path toward clearer, safer error handling. Read the full post to learn how to rethink your approach to robust error handling in TypeScript—and why simply porting a standard Result pattern isn’t enough.
