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);
};
