My port for RS Hash from https://www.programmingalgorithms.com/algorithm/rs-hash?lang=C

RSHash.js

export default function hash(string) {
  const length = string.length;
  let h = 0, a = 63689, b = 378551;
	for (let i = 0; i < length; i++)
	{
		h = (Math.imul(h, a) + string.charCodeAt(i)) >>> 0;
		a = Math.imul(a, b) >>> 0;
	}
	return h;
}

verification.md

the original link has the equivalent of the following:

import hash from "./RSHash.js";
const data = "jdfgsdhfsdfsd 6445dsfsd7fg/*/+bfjsdgf%$^";
const value = RSHash(data);

and I checked it on my node env it returns:

2012450421

I know this is not enough, but this is fine for me.
