New in decisions; what is this ( !(true == true) )


( !(true == true) )


That's just saying true is equal to true in value then goes opposite.

You should get a false as response.


true==true is always true. That's simple to interpret.
! operator is "not". So ! true means not true which means false.


Logically there can be differences depending on the type of value that you are comparing and language you are using. For example:

x == false implies x != true, but x != true does not always imply x == false because x can also be some nonsense value.

1 + 1 = 3 is both == false and != true.

7 > cat is neither == false and != true since it is nonsense.

x = null is != true but is not == false.
