Created June 30, 2016 10:44

node-gyp build on android fails, due to ˋ-pieˋ flag counteracting ˋ-rdynamicˋ flag. intended for the [commit discussion](https://github.com/nodejs/node/commit/271201fea935cdf85336736e87c06104ce185f61).

using _this=this to emulate arrow functions is fast but error-prone, requiring non-trivial analysis for use in transpilers. using .bind to emulate arrow functions is simpler, but slow in current engines. using an apply-based partial polyfill (bind) for .bind is fast in v8, slow in other engines.

	// <script>

	/* sample output
	$ node ../bind-for-arrows.html
	_this: 4ms
	.bind: 25ms
	bind: 4ms
	_this, calls only: 1ms
	.bind, calls only: 4ms
	bind, calls only: 0ms

clausreinke / interfaces.html

Created February 20, 2013 17:23

JavaScript: generic methods, programming to interfaces, classes implementing interfaces; a sketch (load in browser or run with nodejs)

	// see console output <script>

	// quick hack of classes implementing interfaces, just to give the idea; for a
	// proper design, feel free to use better syntax, (Weak)Maps, unique symbols, ..;
	//
	// the core idea is to relate interfaces to classes that implement them, in
	// such a way that the relevant implementations of interface methods can be
	// extracted systematically in generic code

	var Mappable = {}; // interface, to be implemented by classes;
