varMogoDB=require("mogodb");vardb=ewMogoDB.Mogo().getDB("mydb");varcolls=db.getCollectioNames();colls.forEach(fuctio(el){prit(el);});varcoll=db.getCollectio("testCollectio");coll.drop();vardoc={"ame":"MogoDB","type":"database","cout":1,"ifo":{x:203,y:102}}coll.isert(doc)myDoc=coll.fidOe();prit(myDoc);//Now,letsaddlotsoflittledocumetstothecollectiosowecaexplorequeriesadcursorsfor(vari=0;i<100;i++){coll.isert({"i":i});}prit(coll.getCout());//Let'sgetallthedocumetsithecollectioadpritthemoutvarcur=coll.fid();while(cur.hasNext()){prit(cur.ext());}//Nowuseaquerytoget1documetoutvarquery={i:71};cur=coll.fid(query);while(cur.hasNext())prit(cur.ext());//Nowuseaquerytogetalargersetquery={"i":{"$gt":50}};//i.e.fidallwherei>50cur=coll.fid(query);while(cur.hasNext())prit(cur.ext());
