In computing, memoization or memoisation
is an optimization technique used primarily
to speed up computer programs by storing
the results of expensive function calls and  
returning the cached result when the same
inputs occur again.

I bundled these up into groups and wrote some thoughts about why I ask them!

If these helped you, I'd love to hear about it!! I'm on twitter @vcarl_ or send me an email [email protected]

• How long will it take to deploy my first change? To become productive? To understand the codebase?
• What kind of equipment will I be provided? Will the company pay/reimburse me if I want something specific?

Name of thing	Sorta like...	Mounted?	Can you even setState?	What would you say... ya do here?
constructor	initialize()	nope	nope	init stuff NO side effects
componentWillMount	beforeDomReady()	nope	yeah but don't	Only needed in createClass now use constructor for most things
render	render	nope	please no	render stuff and don't set any state please
componentDidMount	domReady()	yup	yup	DOM is a go init jQuery plugins dispatch stuff
componentWillReceiveProps	onChange()	yup	yup
