There should be a `timeout()` or `delay()` method on the `Promise` object for a cleaner way to add a delay in an async code block.

`await Promise.timeout(1000);`

equivalent to

`await new Promise(t => setTimeout(t, 1000));`

`setTimeout` isn't in the language, however, and I suspect there will be a lot of pushback if adding any kind of "timer" is attempted.

+1 to standardize setTimeout among engines and Promise.timeout if possible.

duktape has example-implementation of eventloop/setTimeout in pure javascript which could serve as polyfill [1]. even if engines implement it suboptimally (duktape example is O(n) timer-insertion), its still better than not having setTimeout at all.
