How to deal with asynchronous exception gracefully in js

setTimeout(() => {
    throw new Error("Whoops!");
}, 1000);

For example, in the above scenario, the outer try-catch and other methods must not be handled, and window.onerror is not considered.

In addition to using Promise.reject to rewrite the above code as

new Promise((resolve, reject) => {
    setTimeout(() => {
        reject("Whoops!");
    }, 1000);
}).catch(/* errorHandle */)

Or is there any alternative to try-catch inside setTimout?

async / await?

setTimeout(() => {
    try {
        throw new Error("Whoops!");
    } catch {
        // handle error
    }
}, 1000);

like this?

async / await + try - catch

There is also an inelegant

window.addEventListener('unhandledrejection', function (err) ());
