/*
	// This application helps you convert roman numerals to numbers or vice-versa
*/

// First install the package @ "npm install cr-numeral"
// Then import or require the package in your application
const {
  convertNumberToRoman: cnr,
  convertRomanToNumber: crn,
} = require("cr-numeral");
// OR
const cnr = require("cr-numeral").convertNumberToRoman;
const crn = require("cr-numeral").convertRomanToNumber;

// Define your variables
const number = 2021;
const numeral = "MMMXXV"; // Case-insensitive

// Use your package/module
const toRoman = cnr(number);
const toNumber = crn(numeral);

// Log or use your result
console.log(toRoman, toNumber);

			// Converting a number to Roman Numeral
const { convertNumberToRoman } = require('cr-numeral');
// OR
const convertNumberToRoman = require('cr-numeral').convertNumberToRoman;
