/**
	* 42.js - quickjs bytebeat isolated loader stub, named after the famous 42 melody
	* code: @Dobby233Liu
	* WTFPL
	* fill up the code(t) section, build using qjsc https://bellard.org/quickjs/ then pipe to anything eg. aplay
	* i recommend use node.js more than quickjs, its better, and quickjs is in beta.
		* example program using node.js: bytebeat.jsV2.0 https://pastebin.com/xwtRgcfV
	* gist: https://gist.github.com/Dobby233Liu/157e2438dcfb7a31209616404b301759
