I left out parseInt, but this code still seems to work????

Math.floor(Math.random()) + 1; var userNumber = prompt('pick a number '); var randomNumber = Math.floor(Math.random() * userNumber) + 1; alert( randomNumber + ' is between 1 and ' + userNumber );

When using binary operators, javascript will use type coercion to try and make your code work and not give an error, javascript is very forgiving.

Run these in the console and see what happens

'25' + 5
25 * '5'
'25' - 5
