// [6, 12]
import P from '@antfu/p'

const p = P()

// collect promises that are not necessarily needed to be resolved right away
p.add(promiseTask1)

someOtherTasks()

p.add(promiseTask2)
p.add(promiseTask3)

// resolve all collected promises
await p
// => Promise.all([promiseTask1, promiseTask2, promiseTask3])
import P from '@antfu/p'

// limits the number of concurrent tasks
await P(myTasks, { concurrency: 5 })
