ds.utils

The ds.utils module is a collection of algorithms that don't fit anywhere else.

hash(string)

Computes a hash from a string.

The method implements the Fowler–Noll–Vo or FNV hash algorithm, designed primarily for hash table and checksum use (non-cryptographic). See Wikipedia, Fowler–Noll–Vo hash function for an explanation of this algorithm and Which hashing algorithm is best for uniqueness and speed? for a comprehensive comparison of various hash algorithms.

Params:

• String string The string to be hashed.

Returns:

• String Returns the hash as a base36 encoded number.

hashObject(object)

Computes a hash from the enumerable properties of an object.

The method uses the Fowler–Noll–Vo hash algorithm provided by ds.utils.hash.

Examples:

ds.utils.hashObject({x: 1, y: 2});
// => "3hr02ufj2cg"

ds.utils.hashObject({x: 2, y: 1});
// => "-4jxzz8puql0"

Params:

• Object object The object to be hashed.

Returns:

• String Returns the hash as a base36 encoded number.
