< – Returns true if the value on the left is less than the value on the right
<= – Returns true if the value on the left is less than or equal to the value on the right
> – Returns true if the value on the left is greater than the value on the right
>= – Returns true if the value on the left is greater than or equal to the value on the right
&& – (And) Returns true if both values are true.
|| – (Or) Returns true if either value is true
