What is async-each?

The async-each package is a small, zero-dependency utility module for Node.js that provides a simple way to iterate over an array asynchronously. It allows you to apply a function to each item in an array in parallel, without waiting for the previous function call to complete, making it useful for performing IO-bound tasks or operations that are CPU-intensive but can be run concurrently.

What are async-each's main functionalities?

Asynchronous iteration over an array

This feature allows you to asynchronously process each item in an array. The provided code sample demonstrates how async-each can be used to log each item in an array with a delay of 1 second between each log, simulating an asynchronous operation like reading files or making HTTP requests.

const asyncEach = require('async-each');
const myArray = [1, 2, 3, 4];
asyncEach(myArray, (item, callback) => {
  setTimeout(() => {
    console.log(item);
    callback();
  }, 1000);
}, (err) => {
  if (err) throw err;
  console.log('All items have been processed.');
});
