\u00c8 disponibile una nuova versione del motore JavaScript elk 2.0.9, progettata per l'uso in sistemi con risorse limitate, come microcontrollori, incluse le schede ESP32 e Arduino Nano con 2 KB di RAM e 30 KB di Flash. Per far funzionare la macchina virtuale fornita, sono sufficienti 100 byte di memoria e 20 KB di spazio di archiviazione. Il codice del progetto \u00e8 scritto in linguaggio C e distribuito sotto licenza GPLv2. Per compilare il progetto \u00e8 sufficiente un compilatore C \u2014 non sono utilizzate dipendenze aggiuntive. Il progetto \u00e8 sviluppato dagli sviluppatori del sistema operativo per dispositivi IoT Mongoose OS, del motore JavaScript mJS e di sistemi embedded. server web<\/a> Mongoose (utilizzato in prodotti di aziende come Siemens, Schneider Electric, Broadcom, Bosch, Google, Samsung e Qualcomm). <\/p>\n

L'obiettivo principale di Elk \u00e8 la creazione di firmware per microcontrollori in JavaScript, che svolgono varie attivit\u00e0 di automazione. Il motore \u00e8 anche adatto per incorporare gestori in JavaScript in applicazioni in C\/C++. Per utilizzare il motore nel proprio codice, \u00e8 sufficiente inserire nel tree di sorgenti il file elk.c, includere il file di intestazione elk.h e utilizzare la chiamata js_eval. \u00c8 consentita la chiamata da script JavaScript a funzioni definite nel codice C\/C++, 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 allocazione dinamica della memoria. <\/p>\n

In Elk \u00e8 implementato un sottoinsieme limitato, ma sufficiente, per la creazione di scenari operativi, delle specifiche Ecmascript 6. In particolare, \u00e8 supportato un set base di operatori e tipi, ma non \u00e8 previsto il supporto per array, prototipi, espressioni this, new e delete. Si consiglia di utilizzare let invece di var e const, e di sostituire do, switch e for con while. Non \u00e8 fornita una libreria standard, ovvero non ci sono oggetti come Date, Regexp, Function, String e Number.
