Benchmark: RegExp inside vs outside loop

Script Preparation code:

const SIZE = 100000;
var chars = new Array(SIZE);
for (let index = 0; index < SIZE; index++) {
  chars[index] = String.fromCodePoint(
    Math.floor( Math.random() * 0x80 )
  );
}
var newChars = new Array(SIZE);

Tests:

Outside, literal
const regexp = /[\x00-\x1f\x7f]/g; for (const char of chars) { newChars.push(char.replace(regexp, "")); } console.log(newChars);
Inside, literal
for (const char of chars) { newChars.push(char.replace(/[\x00-\x1f\x7f]/g, "")); } console.log(newChars);
Outside, object
const regexp = new RegExp("[\x00-\x1f\x7f]"); for (const char of chars) { newChars.push(char.replace(regexp, "")); } console.log(newChars);
Inside, object
for (const char of chars) { newChars.push(char.replace(new RegExp("[\x00-\x1f\x7f]"), "")); } console.log(newChars);
