The result of the operation !(true && false || true) will be:

The result of the operation “!(true && false || true)” will be “false”.

To evaluate this expression, let’s break it down step by step:

1. The innermost part of the expression is the logical AND operation “true && false”, which evaluates to “false”. This is because both operands need to be true for the logical AND to return true.
2. Next, we have the logical OR operation “false || true”, which evaluates to “true”. This is because at least one of the operands needs to be true for the logical OR to return true.
3. Finally, we have the logical NOT operation “!true”, which negates the result and returns the opposite. Since the result of the previous step is “true”, the logical NOT operation returns “false”.

Therefore, the result of the operation “!(true && false || true)” is “false”.

To illustrate this in code:

console.log(!(true && false || true)); // Output: false
