How to use Array.prototype.filter with async?

by

There is no way to use filter with an async function (at least that I know of).
The simplest way that you have to use filter with a collection of promises is to use Promise.all and then apply the function to your collection of results.
It would look something like this:

const results = await Promise.all(your_promises)
const filtered_results = results.filter(res => //do your filtering here)

Hope it helps.
