This week at work I was comparing 2 lists from 2 different sources. I frequently perform tasks like this, and always end up writing the same comparison code over and over.
One night after work, I decided to write a simple web app to do the list comparisons for me.
As of now, the app has the following features:
other operations: sort, reverse, unique, trim
uses the Ace Editor (instead of default textarea elements)
uses Twitter Bootstrap
responsive design: 4 different display sizes will change the layout
live editing: the results/counts will be updated as you add new items to lists
a logo visualization of the currently selected comparison operation
using Web Workers (when available) to support larger datasets
