Using RomanNumber class

Instance creation

It's encouraged to instantiate a new value by using the new constructor like demonstrated below:

var romanNumber1 = new RomanNumber(‘XX’);
var romanNumber2 = new RomanNumber(40);

console.log(romanNumber1.toInt()); // => 20
console.log(romanNumber1.toString()); // => ‘XX’

console.log(romanNumber2.toInt()); // => 40
console.log(romanNumber2.toString()); // => ‘XL’

Errors thrown

There are 3 custom errors thrown:

• invalid range - tried to create a new instance with an invalid value. The value must be between 1 and 3999.
• value required - a value needs to be passed when creating a new instance. null, undefined or '' are not valid values.
• invalid value - there was an error trying to parse the roman literal. Please review it.
