Get the hash of a string
Uses the non-cryptographic hash function FNV-1a.
Similar to Java's String#hashCode().
$ npm install @sindresorhus/string-hash
const stringHash = require('@sindresorhus/string-hash');
stringHash('🦄🌈');
//=> 582881315
stringHash('👌😎');
//=> 879086135
It returns the hash as a positive integer.

I recently encountered a similar use case (went for crc16 btw) where the hash had to be provided as a 16-bit number. Given JS-numbers are 64 bits and FNV-1a allowing variable bit length up to 1k I could see this as a useful configurable parameter defaulting to 64.
What do you think?
While looking for a package that generates FNV hashes, I came upon both @sindresorhus/string-hash and @sindresorhus/fnv1a. I got rather confused trying to find a relevant difference between them, so I fully read through both readme files, then finally the source code itself, where it turned out that this package is merely a one-line wrapper around the other one.
I'm not really sure what the rationale behind this is, but maybe you could add a short sentence to the readme files so that later visitors don't get confused in the same way I did.
Why is this module a re-export of @sindresorhus/fnv1a?
I would assume because of the understandable package name.
