Jet Propulsion Laboratory - scientific institution making research and development for NASA. Their portfolio includes such famous missions as Curiosity Mars rover and Voyager probe which left solar system after 25 years of flight and still providing scientific information. High level of automation and long duration of missions led to superior demands to software quality. As a result of JPL amazing experience a set of code guidelines was developed and published recently. Since demands to web-driven software constantly increase and more critical tasks are entrusted to JavaScript, lets apply NASA coding guidelines to JavaScript / HTML applications for higher performance, reliability and the better world.
