## Installation

    npm install generator-function

## Description

Like `Function`s, one could create generator functions from a JavaScript string
through a special constructor called `GeneratorFunction`. However, the
constructor function is [not available as a global][mdn], so one has to use the
`constructor` property of an existing generator function.

This module makes it easy to do so, and falls back gracefully when a runtime
not supporting generator functions is encountered.

[mdn]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/GeneratorFunction#Summary


## Usage

On a platform supporting generator functions:

```js
var GeneratorFunction = require('generator-function')

var generatorFunction = new GeneratorFunction('arg1', 'yield arg1')
var generator = generatorFunction(1)

generator.next()
//=> { value: 1, done: false }
generator.next()
//=> { value: undefined, done: true }
```

On a runtime that does not support them:

```js
var GeneratorFunction = require('generator-function')

GeneratorFunction
// => undefined
```

Expose the GeneratorFunction constructor if supported by the runtime.

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.
