Benchmark: Asterisk map replace vs stored regex replace vs make an array replace

Script Preparation code:

var re = /./gi;
function mapReplace(value) {
  return value.split("").map((x, index, arr) => "*").join("")
}

function makeArrayReplace(value) {
  return (new Array(value.length)).fill("*").join("");
}

function regexReplace(value) {
  return value.replace(re, "*");
}

Tests:

Map replace
const input = "abcdefghijklmnopqrstuvwxyz"; mapReplace(input);
Regex replace
const input = "abcdefghijklmnopqrstuvwxyz"; regexReplace(input);
Make array replace
const input = "abcdefghijklmnopqrstuvwxyz"; makeArrayReplace(input);
