    Try:

    alert(`The result is ${eval(`${num1} ${operator} ${num2}`)}`);

    Backticks instead of single quotes when using template literals.
    That said, I would caution against using eval(), as it can execute arbitrary code and might pose security risks if used with user input.

    Slightly tilt your single quotes and voila!
