True Myth / task / all

Function: all()

Call Signature

all(tasks): Task<[], never>

Given an array of tasks, return a new Task which resolves once all tasks successfully resolve or any task rejects.

Examples

Once all tasks resolve:

import { all, timer } from 'true-myth/task';

let allTasks = all([
  timer(10),
  timer(100),
  timer(1_000),
]);

let result = await allTasks;
console.log(result.toString()); // [Ok(10,100,1000)]

If any tasks do not resolve:

let { task: willReject, reject } = Task.withResolvers<never, string>();

let allTasks = all([
  timer(10),
  timer(20),
  willReject,
]);

reject("something went wrong");
let result = await allTasks;
console.log(result.toString()); // Err("something went wrong")
