## Hint: 1

• Creating an array with the Roman Numerals and one with the decimal equivalent for the new forms will be very helpful.

## Hint: 2

• If you add the numbers that go before the new letter is introduced, it will save you plenty of code, like values for 4, 9, and 40.

# Code Solution:

var convert = function(num) {

// Create arrays with default conversion with matching indices.
var decimalValue = [ 1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1 ];
var romanNumeral = [ 'M', 'CM', 'D', 'CD', 'C', 'XC', 'L', 'XL', 'X', 'IX', 'V', 'IV', 'I' ];

// Create a copy of num to work on and an empty string variable for the final roman number
var numCopy = num;
var romanized = '';

// Loop through the indices of the decimalValue array.
for (var index = 0; index < decimalValue.length; index++) {
// Continue to loop while the value at the current index will fit into numCopy
while (+decimalValue[index] <= numCopy) {
// Add the Roman numeral & decrease numCopy by the decimal equivalent.
romanized += romanNumeral[index];
numCopy -= decimalValue[index];
}
}

return romanized;
};
