Array Parallel

Call an array of asynchronous functions in parallel

API

parallel(fns[, context[, callback]])

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:

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)

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.
