Script Preparation code:
var data = [ "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29" ]
Tests:
Map
var map = new Map(data.map((v, i) => [String(i), v])); let count = 0 for (let i=0; i<data.length; i++) { count += parseInt(map.get(String(i))) }
array 1
var array = data; let count = 0 for (let i=0; i<data.length; i++) { count += parseInt(array[parseInt(String(i))]) }
object 1
var object = Object.assign({}, data) let count = 0 for (let c=0; c<1000; c++) { for (let i=0; i<data.length; i++) { count += object[String(i)] } }
object 2
var object = {...data} let count = 0 for (let c=0; c<1000; c++) { for (let i=0; i<data.length; i++) { count += object[String(i)] } }
array 2
var array = data; let count = 0 for (let i=0; i<data.length; i++) { count += parseInt(array[String(i)]) }
