Section 2.5 Dynamic Behavior Changes: Changing An Instance’s Class and Dynamic Inheritance

tl;dr

Sometimes the behavior of an instance of a data type can be divided into several different “modes” of behavior or implementation…

console.log wrap resolving for your wrapped console logs

What I really get frustrated by is that I cannot wrap console.* and preserve line numbers

Recent improvements to the ClojureScript compiler have greatly simplified setting up development versus production outputs.

This example uses Figwheel as something that you want to exclude for production, but the pattern is general.

With this simple setup you only need one html file/view and it will work for developement and production.

	// Have some complicated non-React widgets that manipulate DOM?

	// A dumb non-react widget that manually manage some DOM node that
	// represent a list of items
	function NonReactWidget(node) {
	this.node = node;
	}
