// assumes you add a timestamp field to each record (see Firebase.ServerValue.TIMESTAMP)
// pros: fast and done server-side (less bandwidth, faster response), simple
// cons: a few bytes on each record for the timestamp
var ref = new Firebase(...);

nest.js

A multi-level groupBy for arrays inspired by D3's nest operator.

Nesting allows elements in an array to be grouped into a hierarchical tree structure; think of it like the GROUP BY operator in SQL, except you can have multiple levels of grouping, and the resulting output is a tree rather than a flat table. The levels in the tree are specified by key functions.

See this fiddle for live demo.

If you want to get the difference between two branches, say master and branch-name, use the following command: git diff master..branch-name

If you want that same diff in a patch, because patches are handy, just add the output redirect: git diff master..branch-name > branch-name.patch

If you need to import that patch into something like Crucible then you'll need to get rid of the a and b prefixes that git adds: git diff --no-prefix master..branch-name > branch-name.patch
