Why is the error handler not working?

Question

```

new Promise(function(resolve, reject) {
setTimeout(() => {
throw new Error("Whoops!");
}, 1000);
}).catch(alert);

````

Can anyone explain why the error handler is not working here? It works without settimeout. [Please don't paste random links]. Thanks.

Answer 1

NBinte This appears to be relevant.

https://stackoverflow.com/questions/48969591/why-promise-can-not-catch-the-error-throw-by-settimeout

In short, catch fails to catch the thrown error since the method is executed in a different stack frame. I am not too knowledgeable about how the stack operates, but the thread I linked includes an answer which go into those details. The second answer explains how you need to call 'reject' instead.

Answer 2

Try using throw and catch inside the method
