Mashoko akawanda akadaro okutanga (kana kuti okutanga) ari muJ anoshanda sezviratidzo zvemasvomhu, nechidimbu kana kuti makoroni zvinowedzera zvinoreva mavara makuru aripo. Uyewo, mavara mazhinji ayo mune mimwe mitauro anowanzodikanwa kuiswa pamwe chete (akadai se [] {} "" `` kana <>) anobatwa naJ semashoko akazvimirira kana, kana akaiswa, semidzi yechiratidzo chimwe chete chemashoko ane mavara akawanda.
J inodzivisa kushandisa mavara chaiwo anodikanwa muAPL nokushandisa panzvimbo pezvo zviratidzo zveASCII bedzi nokuzvibatanidza nedonhwe nekoloni. Ikoku kunoita kuti kuve kuri nyore zvikuru kutaipa pane keyboard yenguva dzose.
