Reduxjs is a very simple js library. So, create an index.html in your Desktop with this content
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/redux/3.7.2/redux.js"></script>
</head>
<body>
<div id="app">
</div>
</body>
</html>
Open the file in your browser. In your js console, as you type Re, it'd autocomplete as Redux. Meaning we have access to the redux class, let's use it.

Cool, next
