dift
Super fast list diff algorithm. Highly optimized for operations common in virtual DOM based UI systems, specifically: prepend, append, reverse, remove all, create all. However, it performs very well in the worst case (random rearrangement) as well.
Without really researching it or benchmarking, i'm going to invoke Cunningham's Law and say that it is the fastest key-based list diff algorithm in existence for this particular application.
Installation
$ npm install dift
