Challenge: Use Advanced JavaScript in React Render Method

Link to the challenge:

What is this stressed out cook doing wrong?

2

It looks like you didn’t finish the challenge. Where it says
“Finally, insert the answer const inside the p tags.” It looks like you did not do this.

3

Am I just supposed to put the word “answer” in those brackets?

4

Yes you need to do just that. Otherwise, how will the choosen answer gets displayed.

okay, I did, but it still says

When MagicEightBall is first mounted to the DOM, it should return an empty p element.

When text is entered into the input element and the button is clicked, the MagicEightBall component should return a p element that contains a random element from the possibleAnswers array.

6

Are you sure, you put the “answer” in curly braces like this : {answer}
Otherwise, you might be putting “answer” as just a string instead of a variable.

7

oh! Okay, just a second.

8

Naw! It still won’t work!

Can you paste your current code. You might be missing something.

        </button><br />
        <h3>Answer:</h3>
        <p>
          { /* change code below this line */ }
<p>{answer}</p>
          { /* change code above this line */ }
        </p>
      </div>
    );
  }
};```

You are putting extra “p”. There is already a “p” tag wrapping the answer.
Do: {answer} instead of
<p>{answer}</p>
