Fast and simple insecure string hash for JavaScript

simple-hash.js

// This is a simple, *insecure* hash that's short, fast, and has no dependencies.
// For algorithmic use, where security isn't needed, it's way simpler than sha1 (and all its deps)
// or similar, and with a short, clean (base 36 alphanumeric) result.
// Loosely based on the Java version; see
// https://stackoverflow.com/questions/6122571/simple-non-secure-hash-function-for-javascript
const simpleHash = str => {
  let hash = 0;
  for (let i = 0; i < str.length; i++) {
    const char = str.charCodeAt(i);
    hash = (hash << 5) - hash + char;
    hash &= hash; // Convert to 32bit integer
  }
  return new Uint32Array([hash])[0].toString(36);
};

For anyone landing here from google, I plotted this hashing function distribution using this stackoverflow answer's methodology, below are the results. I've also been benchmarking the performance, murmur2 has the best performance in JS, so use that function if you need one.
