Node.js source code of require() function

Question

According to the document (https://nodejs.org/api/globals.html), require() function is one of the global objects/functions. But I'm having a hard time finding its source code on Github. Are they written in JS or C++? I was looking for them in https://github.com/nodejs/node project.

To answer my own question, I think it's defined in loader.js. And you can see it's implemented for all modules. It seems to be mapped to global.require in node.js

This seems to be it (in node/lib/internal/modules/cjs/helpers.js).
