Convert numbers into different numeral systems and back
npm i charcoder --save
const Charcoder = require('charcoder')
const hex = new Charcoder()
hex.encode(100) // '64'
hex.decode('64') // 100
const {
Charcoder,
B62
} = require('charcoder')
const b62 = new Charcoder(B62)
b62.encode(100) // '1C'
b62.decode('1C') // 100
You can use any characters to create your own numeral system. For example -, + and the word hey.
const Charcoder = require('charcode')
const custom = new Charcoder('-' + '+' + 'hey')
custom.encode(100) // 'y--'
custom.decode('y--') // 100
const Charcoder = require('charcoder')
// or
const { Charcoder } = require('charcoder')
