Taming Async/Await Errors with IIFEs
February 5, 2026
When you start using `async/await` inside modules or scripts that aren't already wrapped in an async function (like the main function in a Node script), you might hit frustrating syntax errors. A neat trick is wrapping your top-level asynchronous logic in an Immediately Invoked Function Expression (IIFE). Just define `(async () => { /* your code here */ })();`. This gives you a safe, contained scope where you can use `await` freely and handle potential runtime errors cleanly using standard `try...catch` blocks right at the entry point of your script.
