I don't know what's wrong with my code 

<script>
var correctGuess = false;
var randomNumb = Math.floor(Math.random()*6)+1; 

var randonNumb = parseInt(randonNumb);
var inputNumb = prompt("Can you type random number?");
if (inputNumb === randomNumb) {
  correctGuess = true;
} 

if (correctGuess) {
  document.write('You got it!')
} else {
  document.write ('Sorry. The number was ' + randomNumb)  
}

/*       or          */

var correctGuess = false;
var randomNumb = Math.floor(Math.random()*6)+1; 
var inputNumb = prompt("Can you type random number?");

if (parseInt(inputNumb) === randomNumb) {
  correctGuess = true;
} 

if (correctGuess) {
  document.write('You got it!')
} else {
  document.write ('Sorry. The number was ' + randomNumb)  
}
</script>

All I did differently is that I didn't put pareInt inside a conditional statement when I did put pareInt inside conditional statement it worked I just don't understand what is the difference.

inputNumb is of type string whereas randomNumb is an integer, therefore without parseInt applied to inputNumb that deep equality conditional statement will never be true. Remember for it to be true, both value and type must be the same. Also, every user input collected through prompt is always a string.
