No-bullshit, ultra-simple, 40-lines-of-code async parallel forEach function for JavaScript.

We don't need junky 30K async libs. Really.

For browsers and node.js.

npm install async-each if you're using NPM.

For browsers, just include async-each before your scripts and use global variable asyncEach

• each(array, iterator, callback) — Array, Function, (optional) Function
• iterator(item, next) receives current item and a callback that will mark the item as done. next callback receives optional error, transformedItem arguments.
• callback(error, transformedArray) optionally receives first error and transformed result Array.

var each = require('async-each');
each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
  if (error) console.error(error);
  console.log('Contents for a, b and c:', contents);
});

asyncEach(list, fn, callback); // use global var in browser
