Ingxaki ephambili ngokusebenzisa ukuphindaphinda ukwenza ukubala ukwehla kukuba kunokuba nzima ukulawula ukupakishwa kwezinto eziguquguqukayo. Ukuba i-recursion iba nzulu kakhulu, kunokuba nzima ukulandelela ukuba yeyiphi inguqu ekhoyo ngoku kwisitaki. Oku kunokukhokelela kwiimpazamo okanye ukuziphatha okungalindelekanga.
umsebenzi countdown(inombolo){ ukuba (inani <= 0) {console.log("Konke kwenziwe!"); buya } console.log(inani); inani--; ukubala ukwehla(inani); [/code] Lo ngumsebenzi ophinda-phindayo ozabala ezantsi ukusuka kwinani eligqithiselwe njengengxabano. Ukuba inani lingaphantsi okanye lilingana no-0, liya kuprinta "Konke kwenziwe!" kwaye ubuye. Kungenjalo, iyakuprinta inani langoku, inciphise inani ngo-1, kwaye emva koko ifowunele umsebenzi wokubala phantsi kwakhona ngenombolo entsha.
isalathisi
Isalathiso luhlobo olukhethekileyo lwenguqu egcina indawo ngokulandelelana. KwiJavaScript, isalathisi sinokusetyenziswa ukufikelela kwizinto ezithile zoluhlu okanye into.
IiTuples
I-tuple lulwakhiwo lwedatha olubamba iseti yezinto ezimbini nangaphezulu. KwiJavaScript, ii-tuples zenziwe kusetyenziswa igama elingundoqo le-var kwaye zinokufikelelwa kusetyenziswa ubhalo lwezibiyeli zesikwere. Umzekelo, le khowudi ilandelayo yenza i-tuple equlethe amaxabiso 2 kunye no-3:
var tuple = {2, 3};
Ukufikelela kumba wokuqala kwi-tuple, ungasebenzisa ixabiso lesalathisi sika-0:
ituple[0] = 2;
