Stop running this script? IE 8

On IE 8..

Stop running this script?
A script on this page is causing Internet Explorer to run slowly. If this continues to run, your computer might become unresponsive.

This is on a blank WordPress theme with Bootstrap CSS & JS.
The three JS files (tokenizer, parser, vminpoly) are minified into one file along with Bootstrap. In this order:

1. bootstrap.js
2. tokenizer.js
3. parser.js
4. vminpoly.js

The minified file is in the footer of my theme after including jQuery.

My CSS:

section.banner {height: 90vh;}

I am using BrowserStack to test my local site.

Here is a screenshot of my JS code before being minified with CodeKit
