# async-each
2023-02-08 12:35:10 +00:00
No-bullshit, ultra-simple, 40-lines-of-code async parallel forEach function for JavaScript.
2022-01-21 08:28:41 +00:00
We don't need junky 30K async libs. Really.
For browsers and node.js.
## Usage
2023-02-08 12:35:10 +00:00
`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`
2022-01-21 08:28:41 +00:00
* `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` .
```javascript
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);
});
2023-02-08 12:35:10 +00:00
asyncEach(list, fn, callback); // use global var in browser
2022-01-21 08:28:41 +00:00
```
