The hash function can be used to create a numeric hash from a given string. If you want to constraint the hashing space you can pass an optional modulus.
const id = hash("ABC"); // 64578
const small_id = hash("ABC", 10); // 8
The numberToBase util will transform any number to an arbitrary base represented as a string of characters (e.g. the base two could be ["0", "1"]). This can be useful to convert between numeric representations or to compress big numbers. It defaults to a base of 26 elements formed of the English alphabet.
const id_base_26 = numberToBase(hash("ABC")); // cqmv
const id_base_2 = numberToBase(hash("ABC"), ["?", "!"]); //!!!!!???!???!?!
const id_base_2 = numberToBase(8, ["1", "0"]); // 100
