Extra methods for promises for arrays

[![Build Status](https://travis-ci.org/then/array.png?branch=master)](https://travis-ci.org/then/array)
[![Dependency Status](https://gemnasium.com/then/array.png)](https://gemnasium.com/then/array)
[![NPM version](https://badge.fury.io/js/then-array.png)](http://badge.fury.io/js/then-array)

## Installation

    npm install then-array

## API

`ArrayPromise` inherits the entire API of [promise](https://github.com/then/promise) but all methods return instances of `ArrayPromise` where they would've returned instances of `Promise`.  Those methods are:

 - `ArrayPromise.from(value)`
 - `ArrayPromise.all(array) / Promise.all(a, b, c, ...)`
 - `ArrayPromise.denodeify(fn)`
 - `ArrayPromise.nodeify(fn)`
 - `ArrayPromise#then(onFulfilled, onRejected)`
 - `ArrayPromise#done(onFulfilled, onRejected)`
 - `ArrayPromise#nodeify(callback)`

In addition, the following methods are provided with APIs that correspond to the Array equivallents but which support promises everywhere:

 - `ArrayPromise#reverse()` returns a promise for a new array with the elements reversed
 - `ArrayPromise#concat(args...)` if args are arrays or promises for arrays it will return a promise for all the arrays concatenated together.
 - `ArrayPromise#slice(begin[, end])` return a promise for that portion of the array
 - `ArrayPromise#map(fn)` parallel, promised map
 - `ArrayPromise#filter(fn)` parallel, promised filter
 - `ArrayPromise#reduce(fn[, initial])` promised reduce
 - `ArrayPromise#reduceRight(fn[, initial])` promised reduceRight

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
