Hello. I want to submit a code stuff with an explanation. It is not a valid code. Someone can help me to find error?

I'm trying to build a program that change numbers writen in decimal notation.
If we consider each ranges of numbers: unities, 10-es, 100-es and etc,
the pattern is the same.
If we take an array of characters ["a", "b", "c"], we have:
1 --> 'a',
2 --> 'aa',
3- --> 'aaa'
4 --> 'ab',
5 --> 'b',
6 --> 'ba',
7 --> 'baa',
8--> 'baaa',
9-->'ac'.
0 -->''
Now we have as representations of abc:
('I', 'V', 'X');
('X', 'L', 'C');
('C', 'D', 'M');
('M', V with upperscore, X with upperscore ) and etc.
The principe is the same, we need a strategy to replace the combinations
of abc by the roman numeral symbols.
I think that, e.g. if we take the number 257,
The first step is to convert the number to string ‘257’.
The second step is to slplit the string in an array
var list = [‘2’, ‘5’, ‘7’]. his length is “l”.
The third step is to looping through this array and replace
the list [l-1] characters following the first representation of abc,
the next, list [l-2] up to [0] replaced as this.
the fourst step is to join the modified list with .join(‘’).
You can see the Code and if you help me to debugging I'll be grateful!*/
