What stated as a quick project to play with web workers proved to be more useful.
This little app as the name suggests allows you to compare lists and find:
- items in list 1 but not in list 2
- items in list 2 but not in list 1
- items in either list but not in both
- items in both lists
The app makes use of web workers to process large lists but will work with older browsers and Internet Explorer.

Note: The GitHub files use inline web workers so that it will work on the local file system.
