FNV-1a non-cryptographic hash function
FNV-1a has outstanding distribution and collisions are rare.
FNV hashes are designed to be fast while maintaining a low collision rate. The FNV speed allows one to quickly hash lots of data while maintaining a reasonable collision rate. The high dispersion of the FNV hashes makes them well suited for hashing nearly identical strings such as URLs, hostnames, filenames, text, IP addresses, etc.
$ npm install @sindresorhus/fnv1a
