My solution to quiz challenge 1 doest work, but seems everything fine to me

I tried this but it doesn't work. (I type the answer upper case). Any help appreciate! :)

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


var correct = 0;
var answer;
var soluzione;

var domandeSoluzioni = [["what is my name?", "SEMHAR"],["How old am I?", 31],["Where do I live","STOCCOLMA"]];

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

{

answer =parseInt(prompt(domandeSoluzioni[i][0]));
soluzione=domandeSoluzioni[i][1];

if ( answer ===  soluzione)
{ correct  += 1; }

}


print("You got "+correct+" answer(s) correct");

You are running parseInt on your answer from the prompt. This will remove the text from your answer, therefore your non-integer answers will always be wrong. To fix this easily you can remove the parseInt, then change your === to == (when comparing user-input to the answer) This will compare the variable values without comparing the variable types. There are other ways to fix this, but this is the quick/easy path right now.

As a side note you may also want to look into running .toUpperCase() on the user input so the users input is case insensitive.

I see. So in this case , when I have answers that are both text and number, how do I do to have both type of value considered? Do I have to type the number as text ("31") and remove the parseInt? It doesnt seem right... What do you think? Thank you
