Dambudziko guru rekushandisa recursion kugadzira kuverenga nderekuti zvinogona kunetsa kubata stack yezvinosiyana. Kana iyo recursion ikanyanya kudzika, zvinogona kunetsa kuteedzera kuti ndeupi musiyano uripo pane stack. Izvi zvinogona kukonzera kukanganisa kana maitiro asingatarisirwi.
basa countdown(num){kana (nhamba <= 0) {console.log("Zvose zvakaitwa!"); return; } console.log(num); num--; countdown(nhamba); [/code] Iri ibasa rinodzokororwa rinoverengera pasi kubva kunhamba yakapfuura senharo. Kana iyo nhamba iri pasi kana kuenzana na0, inodhinda "Zvese zvaitwa!" uye kudzoka. Zvikasadaro, inodhinda nhamba iripo, ichidzikisa nhamba ne1, uye yobva yadaidza basa rekuverengera zvakare nenhamba itsva.
indekisi
Indekisi imhando yakasarudzika inochengeta chinzvimbo munhevedzano. MuJavaScript, indekisi inogona kushandiswa kuwana zvakati zvinhu zvearoyi kana chinhu.
Tuples
A tuple chimiro che data chinobata seti yezvinhu zviviri kana kupfuura. MuJavaScript, tuples anogadzirwa uchishandisa var keyword uye anogona kuwanikwa uchishandisa sikweya mabhuraketi notation. Semuenzaniso, iyo inotevera kodhi inogadzira tuple ine kukosha 2 uye 3:
var tuple = {2, 3};
Kuti uwane chinhu chekutanga mu tuple, waizoshandisa index kukosha kwe0:
tuple[0] = 2;
