For example they can be used to encode a database integer ID or a specific date.

Ex.

    The date date=2020-01-31T15:01:17.647Z can be passed to a person using this code K62AP58V.

Ex.

    A small-big number 20880 can be written as G40

Ex.

    Big number 7607118767 can be written as 3HT2YEN

    const {
        codeSystem,
        base36
    } = require("humanized-codes");


    // Use base 36 system (36 symbols)
    // 1. encode a date,
    const dateHumanCode = base36.encode(new Date().getTime());
    console.log("Date Human Code => " + dateHumanCode + ", date=" + new Date(base36.decode(dateHumanCode)).toISOString());

    // 2. encode a small or big number,
    const bigNumber = Math.floor(Math.random() * 10000000000);
    const bigNumberHumanCode = base36.encode(bigNumber);
    console.log("Big Number Human Code => " + bigNumberHumanCode + ", decoded=" + base36.decode(bigNumberHumanCode) + "=" + bigNumber);

    // 3. make a composed code.
    const code = `${bigNumberHumanCode}-${dateHumanCode}`;
    const [n, d] = code.split("-");
    console.log("Code: " + code + ", decoded: " + base36.decode(n) + ", " + new Date(base36.decode(d)).toISOString());


    // Use base 16 system (16 symbols, hexadecimal)
    const hexBase = codeSystem(16);
    const dateHexHumanCode = hexBase.encode(new Date().getTime());
    console.log("Date Hex Human Code => " + dateHexHumanCode + ", date=" + new Date(hexBase.decode(dateHexHumanCode)).toISOString());
