First, we built an object in our Javascript, and then we added a question with a certain ID number to that object. We have built 25 questions in total and placed them within our object. The user will receive the quiz task’s outcome at the end of the quiz by utilizing the conditional statements to verify, as the user clicks on any of the alternatives, if and else statements, whether the answer they choose matches the proper response.
