# Array Series [](https://travis-ci.org/component/array-parallel)
|
|
|
|
Call an array of asynchronous functions in parallel
|
|
|
|
### API
|
|
|
|
#### parallel(fns[, context[, callback]])
|
|
|
|
```js
|
|
var parallel = require('array-parallel')
|
|
|
|
parallel([
|
|
function (done) {
|
|
done()
|
|
}
|
|
], this, function (err) {
|
|
|
|
})
|
|
```
|
|
|
|
#### fns
|
|
|
|
`fns` is an array of functions to call in parallel.
|
|
The argument signature should be:
|
|
|
|
```js
|
|
function (done) {
|
|
done(new Error())
|
|
// or
|
|
done(null, result)
|
|
}
|
|
```
|
|
|
|
That is, each function should only take a `done` as an argument.
|
|
Each callback should only take an `Error` as the first argument,
|
|
or a value as the second.
|
|
|
|
#### context
|
|
|
|
Optional context to pass to each `fn`.
|
|
Basically `fn.call(context, done)`.
|
|
|
|
#### callback(err, results)
|
|
|
|
```js
|
|
function (err, results) {
|
|
|
|
}
|
|
```
|
|
|
|
Only argument is an `Error` argument.
|
|
It will be the first error retrieved from all the `fns`.
|
|
`results` will be an array of results from each `fn`,
|
|
thus this could be considered an asynchronous version of `[].map`.
