ruby method block and yield

	# Call foo with a block, but foo just ignores the block
	foo { puts "doesn't call the block" }

	# foo can capture the block

interesting snippet to get the minified key of an object. from react JS

	/**
	* Allows extraction of a minified key. Let's the build system minify keys
	* without loosing the ability to dynamically use key strings as values
	* themselves. Pass in an object with a single key/val pair and it will return
	* you the string key of that single record. Suppose you want to grab the
	* value for a key 'className' inside of an object. Key/val minification may
	* have aliased that key to be 'xa12'. keyOf({className: null}) will return
	* 'xa12' in that case. Resolve keys you want to use once at startup time, then
	* reuse those resolutions.

What a template might look like

	# Creating and Using Regexps

	You're reading this because you want to use regular expressions when you code.
	So this is probably a good time to tell you how to represent and use regular
	expressions in your programs.

	The good news is that most languages make it easy to use regular expressions.
	The bad news is that each language does it differently.
