L'obiettivo principale di Elk \u00e8 la creazione di firmware per microcontrollori in linguaggio JavaScript, eseguendo vari compiti di automazione. Il motore \u00e8 anche adatto per l'inserimento di gestori in JavaScript in applicazioni C\/C++. Per utilizzare il motore nel proprio codice, basta inserire il file elk.c nell'albero dei sorgenti, includere il file di intestazione elk.h e utilizzare la chiamata js_eval. \u00c8 consentito richiamare funzioni definite nel codice C\/C++ dai script JavaScript, e viceversa. Il codice JavaScript viene eseguito in un ambiente protetto e isolato dal codice principale, utilizzando un interprete che non genera bytecode e non utilizza assegnazione dinamica della memoria. <\/p>\n
