# f-throttle [![Build Status](https://travis-ci.org/meryn/f-throttle.png?branch=master)](https://travis-ci.org/meryn/f-throttle) [![Dependency Status](https://david-dm.org/meryn/f-throttle.png)](https://david-dm.org/meryn/f-throttle)

Limit concurrency of a function returning a promise.

## Usage

```javascript
var throttle = require("f-throttle")
var throttledFn = throttle(concurrency, anyFn)
```

`throttleFn` functions like `anyFn`, but throttled to a concurrency of `concurrency`, where concurency is a number equal or higher than one.

### Notes

* `throttledFn` returns a promise.
* `anyFn` must return a promise. If it does not, the promise returned by `throttledFn` will be rejected.
* You may pass any number of arguments
* Function context is preserved, so can work for when throttling a function that's a method for an object.
* When you throttle a function to a concurrency of 1, this results in execution in a serial fashion.

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.
