## README

# Priority Queue

This module allows you to run a queue of callback while on the browser's idle time making sure the higher-priority work is performed first.

## Installation

Install the module

```bash
npm install @wordpress/priority-queue --save
```

_This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for such language features and APIs, you should include [the polyfill shipped in `@wordpress/babel-preset-default`](https://github.com/WordPress/gutenberg/tree/HEAD/packages/babel-preset-default#polyfill) in your code._
