UserScript for refreshing the Walgreens covid vaccine appointment page

Please note that you must be eligible to get the vaccine. If you are not eligible for the vaccine, this will not help you. In that case the only thing you can do is try showing up at the end of the day at a vaccination site to see if they have any leftovers that need to be used up.

Installation

1. Install the TaperMonkey extension.
2. Add this script.

/**
 * An implementation for Quicksort. Doesn't
 * perform as well as the native Array.sort
 * and also runs the risk of a stack overflow
 *
 * Tests with:
 *
 * var array = [];
 * for(var i = 0; i < 20; i++) {
 *   array.push(Math.round(Math.random() * 100));
