import LimitTask from "limit-task";

const wait = (ms) =>
  new Promise((resolve) => {
    setTimeout(() => {
      resolve();
    }, ms);
  });

const queue = LimitTask(2);

queue(async () => {
  console.log("first tasks added");

  await wait(2000);
  console.log("first tasks completed");
});

queue(async () => {
  console.log("second tasks added");

  await wait(1000);
  console.log("second tasks completed");
});

queue(async () => {
  console.log("third tasks added");

  await wait(3000);
  console.log("third tasks completed");
});

the above code will execute maximum of 2 task concurrently. The log output will be as follows:

--> first tasks added --> second tasks added --> one seconds delay --> second tasks completed --> third tasks added --> one seconds delay --> first tasks completed --> two seconds delay --> third tasks completed
