Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Download the latest OSX from App Store.
- The installer will open itself after its download. Do not proceed with install - close it!
- Once downloaded the installer will be available on Applications folder.
Run the following command, taking care to rename the OSX version accordingly and to specify the name of the volume (make sure the command is typed in a single line):

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/<name-of-volume> --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

The prompt will ask for system password...

Install MongoDB on macOS Sierra

This procedure explains how to install MongoDB using Homebrew on macOS Sierra 10.12.
Official MongoDB install documentation: here

Install Homebrew

Installing Homebrew is effortless, open Terminal and enter :
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

	// a loose check, to see if object exists
	if (something) {
	console.log('%c something() is present! ', 'background: #bada55; color: black');
	} else {
	console.log('%c something() is NOT present! ', 'background: #de1e7e; color: white');
	}

	// a strict check, object must be a function
	if (typeof(something) === 'function') {
	console.log('%c something() is present! ', 'background: #bada55; color: black');
