Benchmark: regex replace performance : chaining replace vs table function replace

Script Preparation code:

const HTMLRegex = /[&<>"'`]/g;
const HTMLTable = {
    "&": "&amp;",
    "<": "&lt;",
    ">": "&gt;",
    '"': "&quot;",
    "'": "&#039;",
    "`": "&#96;",
};

function sanitizeTable(text) {
    return text.replace(HTMLRegex, (match) => HTMLTable[match]);
};

function sanitizeChain(text) {
  return text
    .replace(/&/g, "&amp;")
    .replace(/</g, "&lt;")
    .replace(/>/g, "&gt;")
    .replace(/"/g, "&quot;")
    .replace(/'/g, "&#039;")
    .replace(/`/g, "&#96;");
}

Tests:

chain
sanitizeChain(`<div attr="'value&'"></div>`);
table
sanitizeTable(`<div attr="'value&'"></div>`);
