  PREDEFINED_RANGES,

  ReverseCharID
} from 'reverse-char-id'

// OR

// Import without bundler
const {
  REVERSED_PREDEFINED_RANGES,
  PREDEFINED_RANGES,

  ReverseCharID
} = require('reverse-char-id')

const reverseCharID = new ReverseCharID() // Default character range: 0 to 9

console.log(
  `${reverseCharID}`,
  reverseCharID.toString(),
  reverseCharID.toValue(),
  String(reverseCharID)
) // 0 1 2 3

const reverseCharID = new ReverseCharID({
  ranges: [
    REVERSED_PREDEFINED_RANGES['z to a'],
    PREDEFINED_RANGES['0 to 9']
  ],
  lastID: 'c'
})

console.log(
  `${reverseCharID}`,
  reverseCharID.toString(),
  reverseCharID.toValue(),
  String(reverseCharID)
) // b a 0 1
