const { AsyncQueue } = require("@axetroy/async-queue");

import { AsyncQueue } from "@axetroy/async-queue";

const delay = (ms) => new Promise((resolve) => setTimeout(resolve, ms));

const queue = new AsyncTaskQueue({ concurrency: 2 });
// Add task to the queue
queue.enqueue(() => delay(1000).then(() => console.log("Task 1 completed")));
queue.enqueue(() => delay(500).then(() => console.log("Task 2 completed")));
queue.enqueue(() => delay(300).then(() => console.log("Task 3 completed")));
queue.enqueue(() => delay(400).then(() => console.log("Task 4 completed")));

// Wait for all tasks to complete
