Which htmlEntities are used by Facebook, Google or Twitter?

Question

JavaScript

Hello, tell me please.
I use the following function on my project on the frontend to be safe from using xss

function htmlEntities(str) {
    return String(str).replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/"/g, '&quot;');
}

This begs the question, do companies like Google or Facebook or other similar monsters really use the usual replace ? Something hard to believe or do they have their own self-written encoders?
