What is after?

The 'after' npm package is a small utility that helps manage asynchronous operations by executing a callback after a specified number of operations have completed. It is particularly useful for scenarios where you need to wait for multiple asynchronous tasks to finish before proceeding.

What are after's main functionalities?

Execute callback after multiple asynchronous operations

This feature allows you to specify a callback function that will be executed after a certain number of asynchronous operations have completed. In this example, the callback will be executed after three tasks have finished.

const after = require('after');

const done = after(3, () => {
  console.log('All tasks completed');
});

setTimeout(() => {
  console.log('Task 1 done');
  done();
}, 1000);

setTimeout(() => {
  console.log('Task 2 done');
  done();
}, 2000);

setTimeout(() => {
  console.log('Task 3 done');
  done();
}, 3000);
