B2G repo setup and build quickstart

B2G Quickstart for Payments and Identity

Before you begin: You want to do this on a Mac. I have been using Linux for months, and unresolved redraw issues (white screen of death) are killing me. Mac works great. Use OSX.

This sets you up to make two separate targets:

  • One for a desktop [simulator] [1]
  • One for the Unagi [device] [2]

These are the moving parts:

  • [mozilla-inbound repo] [3] clone (hg)

Virtual DOM and diffing algorithm

There was a [great article][1] about how react implements it's virtual DOM. There are some really interesting ideas in there but they are deeply buried in the implementation of the React framework.

However, it's possible to implement just the virtual DOM and diff algorithm on it's own as a set of independent modules.

Streaming iterables

Your friends from pull stream, but in terms of async iterators.

source it

A "source" is something that can be consumed. It is an iterable object.
