Hash Tables & JavaScript Objects

What type of hash function is implemented here?

function hashString(str) {
  let hash = 0;
  for (let i = 0; i < str.length; i++) {
    hash = ((hash << 5) - hash) + str.charCodeAt(i);
    hash = hash & hash;
  }
  return Math.abs(hash);
}

MD5 hash
SHA-1 hash
djb2 hash
This implements the djb2 hash algorithm because: 1) Uses bit shifting for efficient computation, 2) Incorporates character codes sequentially, 3) Provides good distribution for string input, 4) Minimizes collisions through bitwise operations, 5) Returns positive integer suitable for array indexing, 6) Commonly used in hash table implementations, 7) Simple yet effective for basic hashing needs, 8) Balances performance and distribution quality.
