Script Preparation code:
var valueList2 = ["apa", "anya", "gyerek"]; for (var i = 0; i < 14200; i++) { valueList2.push("Apa" + i); }
Tests:
Hashmap
var res2 = new Map(); for (var value of valueList2) { if (!res2.get(value.toLowerCase())) { res2.set(value.toLocaleLowerCase(), value.toLocaleLowerCase()); } }
Dictionary object
var dictionary = {}; for (var i = 0; i < valueList2.length; i++) { var item = valueList2[i].toLowerCase(); if (!dictionary[item]) { dictionary[item] = i; } }
_uniqWith
_.uniqWith(valueList2, (arrVal, othVal) => arrVal.toLowerCase() === othVal.toLowerCase());
