## Install

```sh

$ go get github.com/magicdawn/go-promise-util

```

## API

### package name = putil

use

```go

putil.Map()

putil.Async()

putil.AsyncFactory()

```

### Map

```go

Map(

  items interface{}[],

  fn func(item interface{}, index int, items []interface{}) *promise.Promise,

  concurrency int

) *promise.Promise

```

like node.js `promise.map` / `async.parallelLimit`

### Async & AsyncFactory

```go

sleepUseNewPromise := func(sec int) *promise.Promise {

  return promise.New(func(resolve func(interface{}), reject func(error)) {

    time.Sleep(time.Second * time.Duration(sec))

    resolve(sec * sec)

  })

}

sleepUseAsync := func(sec int) *promise.Promise {

  return promiseUtil.Async(func() interface{} {

    time.Sleep(time.Second * time.Duration(sec))

    return sec

  })

}

sleepUseAsyncFactory := promiseUtil.AsyncFactory(func(args ...interface{}) interface{} {

  sec := args[0].(int)

  time.Sleep(time.Second * time.Duration(sec))

  return sec

})

```
