Can`t I use toLowercase() to variable?

When I use toLowercase() below(variables) code I`m unable to get the result..!

var quiz= [
  ['Your name?','Neil'],
  ['neil`s age',24],
  ['Aim of neil is film maker',true]
];
var answer;
var question;
var response;
var correctanswers = 0;
var html;

function print(message) {
  document.write(message);
}

for(var i = 0; i < quiz.length; i +=1){

  question=quiz[i][0];
  answer=quiz[i][1];
  response = parseInt(prompt(question));
  if(response.toLowerCase()=== answer.toLowerCase()){
    correctanswers+=1;
  }
}

html = "you got "+ correctanswers+" question(s) right?";
print(html);

please paste the code properly

Hey Vineel,

The link you posted isn't working; you just need to use markdown around the code you pasted above, as Siddhant mentioned. There is a markdown cheatsheet when you post or edit your code.

why are you doing this

response.toLowerCase()

It's an integer. Your using a string function on a integer. Remove the .toLowerCase() on the response

My first question`s response is string('neil') and I tried by removing .tolowercase as well but no use...!

where is the documentation for toLowerCase()? I can't even find the documentation for string?
