JSON to Binary encoder/decoder

JSON from/to Binary encoding/decoding that supports the following data types:

• Constant values:
  • undefined
  • null
  • true
  • false
• Numbers:
  • Integers
  • BigInt's
  • Floats
• Strings
• Arrays
• Objects
• Sets
• Maps
• Dates

Usage Example:

import {Json} from "json-binary";

const data = {
    int: 9999,
    float: Math.PI,
    str: "Hello, world!",
    undef: undefined,
    nil: null,
    T: true,
    F: false,
    arr: ['A', 'B', 'C'],
    obj: {
        map: new Map([[1, 2], [3, 4]]),
        set: new Set([7, 8, 9])
    },
    date: new Date()
};

const json = new Json();

const encoded = json.encode(data);

console.log(encoded);

/* Output: Uint8Array(135) [
