Roman Numerals help

1

Hey.
A “num” should be equal to romanKeys. Roman keys is a massive (right?) so I have to turn it into a string to compare. But somehow it doesn’t work. What have I done wrongly?
Code:

function convertToRoman(num) {
  var roman = {
   1:'I',
   2:'II',
    3: 'III',
    4: 'IV',
    5: 'V',
    6: 'VI',
    7: 'VII',
    8: 'VIII',
    9: 'XI',
    10: 'X'
  };
  var x;
 var romanKeys = Object.keys(roman)[1].toString();
  if (num === romanKeys) //this should be true
    {return roman[1];}
  else return false;
}

convertToRoman(2);

Thanks, that work!
But I have yet another problem - I can’t get info from the for loop (even if the loop isn’t actually “working”). Variable “x” stays empty for some reason. Could you pls take a look?
Code:


function convertToRoman(num) {
  var roman = {
   1:'I',
   2:'II',
    3: 'III',
    4: 'IV',
    5: 'V',
    6: 'VI',
    7: 'VII',
    8: 'VIII',
    9: 'XI',
    10: 'X'
  };
  var x=[]; //this x should cointain roman[2], and it works without the for loop
 for (var i=0;i<roman.length;i++){
 var romanKeys = Object.keys(roman)[1];
  if (num == romanKeys)  {
      x.push( roman[2]);
    }
 }
return x.toString();  
}

convertToRoman(2);
