Given the expression +true; !'Lydia'; what will be the outputs?

To evaluate the provided expression, let's break it down step by step.

Firstly, the expression uses the unary plus operator (+) with the boolean value true. The unary plus operator converts the operand to a number. In JavaScript, true evaluates to 1 when converted to a number. Therefore, the first part of the expression, +true, outputs 1.

Next, the expression includes the negation operator (!) applied to the string 'Lydia'. In JavaScript, when a non-empty string is evaluated in a boolean context, it is considered truthy. Applying the negation operator to a truthy value ('Lydia') will give false. Thus, !'Lydia' outputs false.

Putting both outputs together, the expression +true; !'Lydia'; results in the outputs 1 for the first part and false for the second.

The correct answer aligns with this rationale, as it correctly summarizes the outputs of the expressions evaluated.
