Võrgurakendused IV loengu konspekt Javascriptis on array nagu list. Pikkust ei pea määrama. Saab suvalisele indeksile lisada väärtuse, isegi siis, kui olemasoleva array pikkus on väiksem. var words=["rebane","kala","lind"]; words[10]="koll"; Kui javascriptis võrrelda kahe võrdusmärgiga ==, siis javascript üritab v6rduse mõlemad pooled samasse andmetüüpi teisendada ja siis võrdleb neid. Kui on kolm ===, siis ei teisenda tüüpi. null == 0 on näiteks tõene. TypeOf() true ja false väikeste tähtedega. JS converdib true 1-ks ja false'i 0-ks, juhul kui == kasutada. NaN - kui arvutustel tekib mingi viga, st "not available number" Javascripti dictionary vastab java objektidele. Dicte saab panna ka üksteise sisse. Array-sid saab ka sinna sisse panna. Tegelikult array sisse saab ka teisi arraysid panna. Kui panna var ette, siis tekib lokaalne muutuja, kui var-i ei pane, siis globaalne. Kui JS-s on mingi viga, siis brauser ei näita mingit viga.
