    diff – 140byt.es

A diff function in 110 bytes.  It supports changes, additions and deletions.
Nested objects however are unsupported.
The returned diffs can be patched in using this patch function in < 140 kb;
For a full featured diff and patch library in 600 bytes check out dffptch.js.
For more information

See the 140byt.es site for a showcase of entries (built itself using 140-byte entries!), and follow @140bytes on Twitter.

140byt.es is brought to you by Jed Schmidt, with help from Alex Kloss. It was inspired by work from Thomas Fuchs and Dustin Diaz.
