Seen on mastodon (@patak@webtoo.ls), I am excited to see that this old trick is being standardized:

let resolve, reject
const promise = new Promise((res, rej) => {
  ;[resolve, reject] = [res, rej]
})

I’ve been using deno’s standard library’s deferred for a while, and I’ll be happy to switch to Promise.withResolvers() soon 💪
