Prantsuse matemaatik Fabrice Bellard, kes asutas kunagi projektid QEMU, FFmpeg, BPG, QuickJS, TinyGL ja TinyCC, on avaldanud uue JavaScript-mootori sisseehitatud s\u00fcsteemidele \u2014 Micro QuickJS, mis suudab kompileerida ja t\u00e4ita JavaScripti programme, tarbides vaid 10 KB RAM-i. Koos C-raamatukoguga v\u00f5tab mootor ligikaudu 100 KB p\u00fcsiv\u00e4list m\u00e4lu. JavaScripti kompileerimine \u0431\u0430\u0439\u0442\u043aoodiks ja selle eraldi k\u00e4ivitamine on v\u00f5imalik. Projekti kood on kirjutatud C keeles ja levitatakse MIT-litsentsi alusel. <\/p>\n

Mootor toetab JavaScripti keele alamhulka, mis on l\u00e4hedane ECMAScript 5 (ES2019) spetsifikatsioonile, kuid esitab rangemaid n\u00f5udeid koodile, keelates teatavate ebaefektiivsete v\u00f5i vigaseid JavaScripti konstruktsioone. N\u00e4iteks peavad globaalmuutujad olema kohustuslikult deklareeritud v\u00f5tmes\u00f5naga \u00abvar\u00bb, \u00abwith\u00bb kasutamine on keelatud, massiivides ei tohi olla t\u00fchikuid, \u00abnew Number(1)\u00bb deklareerimise vormis initsialiseerimine ei ole lubatud ja eval kaudu ei ole v\u00f5imalik juurde p\u00e4\u00e4seda lokaalsetele muutujatele. <\/p>\n

Micro QuickJS'i j\u00f5udlus on l\u00e4hedane QuickJS'i mootorile, mida on arendatud Fabrice'i poolt alates 2019. aastast. Micro QuickJS'is on kasutatud osa koodist QuickJS'ist, kuid arhitektuur on suuresti erinev ja projekteeritud minimaalsete m\u00e4lutarbimise jaoks. N\u00e4iteks Micro QuickJS kasutab j\u00e4lgivat pr\u00fcgikoguja, samas kui QuickJS'is on rakendatud viidete arvestust. Pr\u00fcgikoguja kulu on vaid m\u00f5ne bitti iga eraldatud m\u00e4luploki kohta. M\u00e4lueralduseks kasutatakse oma allocatorit, mis ei s\u00f5ltu malloc() raamatukogu funktsioonist. <\/p>\n

Teised erinevused QuickJS'ist: ei kasuta steki; virtuaalne masin<\/a>teistsugune sisemine objekti esitus; stringide salvestamine UTF-8 kodeeringus; standardteegi genereerimine kompileerimise ajal ja selle salvestamine p\u00fcsivasse m\u00e4llu, luues RAM-is vaid m\u00f5ned objektid; parser, mis on l\u00e4hedane QuickJS'ile, kuid ei kasuta rekursiooni; bytecode'i genereerimise ja optimeerimise \u00fchendamine \u00fches l\u00e4bimisse (QuickJS'is on mitmeid l\u00e4bis\u00f5ite optimeerimiseks).
