always shows the else conditions. even when guessing is correct!

var guess=prompt('I am guessing a number between 1 and 6'); alert(guess); var browser= (Math.floor(Math.random()*6 +1));

if (guess===browser) {

alert('you guessed the number'+guess+', which was right');}

else {alert('you guessed the number '+guess+ ' , but it was'+ browser); }

Either convert the string to an Int type, or simply use == instead of === for your conditional statement.

Remove the '===' equals, and just stick with '=='.

The reason for this, is the input you are receiving from the prompt returns a string, not an integer.

'3' === 3 is false '3' == 3 is true

Although they are the same numeric value, their Type is different

String === Int false String == Int (maybe true)

The string guess is never going to be identical to the number browser (===). Try toString() on browser.

I think it should be var browser= Math.floor( Math.random() * 6) + 1; Give it a try..
