ECMAScript 2026 introduces Promise.try, a new method that provides a unified entry point for executing both synchronous and asynchronous functions with consistent error handling. It eliminates the need for awkward wrappers like Promise.resolve().then(fn) and converts synchronous throws into rejected promises. The method executes callbacks synchronously while wrapping results in promises, making mixed sync/async APIs cleaner and more predictable. The article includes TypeScript utilities, result wrapper patterns, and compatibility information for modern runtimes.
