hashSeed(seed: string): : number

Summary

FNV-1a–style hash producing a 32-bit unsigned integer from a string. Used purely for seeding — not for cryptographic purposes.

Source Code

function hashSeed(seed: string): number {
  let h = 0x811c9dc5; // FNV offset basis
  for (let i = 0; i < seed.length; i++) {
    h ^= seed.charCodeAt(i);
    h = Math.imul(h, 0x01000193); // FNV prime
  }
  return h >>> 0;
}

No outgoing dependencies.
