Introduction

A set of JavaScript utilities for developing applications on the Obscure Systems. One of the major advantages of JavaScript is that it can run virtually anywhere nowadays. JavaScript also offers excellent maintainability. You can either open the index.html file directly, start a local web server, or deploy the whole project to a website.
