<script> var x = 10; var y = 9; x == y document.write(x); </script>

Question

it doesn't output false can some one please explain why

Answer 1

because you don't write the comparation. You should so something like that

document.write(x==y);

//or

x = (x==y);

before the write.

Answer 2

you didn't give ; after (x==y) :)
