This is my first attempt to work with logic programming in JavaScript this works out to be essentially as direct as possible a translation of Oleg Kiselyov's microKanren from Scheme to JavaScript original: http://okmij.org/ftp/Scheme/sokuza-kanren.scm There are currently some obvious oddities from imperfections in translating and features of Scheme that really don't match with JavaScript Currently conso (and therefore all code that rely on conso) doesn't work as expected in the case of conso(1,lx,[1,2,3]) where lx should be [2,3]. Eitherway it's an okay start for now, and did help me to get a better sense of how unification works in microKanren. Hopefully next up will be a more detailed implementation of miniKanren and hopefully a mini prolog
