Script Preparation code:
function randomString(e) { e = e || 32; var t = "ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz2345678", a = t.length, n = ""; for (i = 0; i < e; i++) n += t.charAt(Math.floor(Math.random() * a)); return n } var str1 = randomString(100) var str2 = randomString(100000)
Tests:
slice-1
var result1 = Array.from(str1.slice(1, 3)).reduce(function (previousValue, currentValue, index, array) { return previousValue + currentValue; }) var result2 = Array.from(str1.slice(4, 6)).reduce(function (previousValue, currentValue, index, array) { return previousValue + currentValue; }) var result3 = Array.from(str1.slice(7, 10)).reduce(function (previousValue, currentValue, index, array) { return previousValue + currentValue; })
slice-2
var result1 = Array.from(str2.slice(1, 30000)).reduce(function (previousValue, currentValue, index, array) { return previousValue + currentValue; }) var result2 = Array.from(str2.slice(28999, 69999)).reduce(function (previousValue, currentValue, index, array) { return previousValue + currentValue; }) var result3 = Array.from(str2.slice(67000, 99999)).reduce(function (previousValue, currentValue, index, array) { return previousValue + currentValue; })
