Download Microsoft Edge VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
Download Virtualbox and import the Edge VM image.

Then in the VM:

Install guest addons in the VM
Download & install latest NVDA from nvaccess.org
Download & install SharpKeys and use it to map left an alternative key (eg. Left Ctrl) to the Insert key. This is needed because Macs do not typically have an “Insert” key which is the prefix for many NVDA commands.

Three python diff libraries were evaluated for comparing resource revisions.

Understanding Immutable.Record

Functional programming principles and with it immutable data are changing the way we write frontend applications. If the recent de-facto frontend stack of React and Redux feels like it goes perfectly together with immutable data, that's because it's specifically designed for that.

There's several interesting implementations of immutable data for JavaScript, but here I'll be focusing on Facebook's own Immutable.js, and specifically on one of i
