The proposed Safe Assignment Operator (`?=`) in JavaScript aims to simplify error handling by reducing the need for traditional try-catch blocks. This operator transforms function results into a tuple, improving code readability and consistency across APIs. It also automatically handles errors, enhancing security. Inspired by constructs in languages like Go, Rust, and Swift, it supports integration with Promises and async functions and offers customizable error handling via `Symbol.result`.
