Hi! I have 1 question about React render method: inside my

App.js file, I have this code:
return (
<QuizContextProvider>
{
(createQuiz) ? (
<div></div>
) : (
<div>
<Modal/>
<Question question={questions[questionNumber]} next={goToTheNext} />
</div>
)
}
{console.log(createQuiz)}
</QuizContextProvider>
);
}
It works fine but the console.log part outputs createQuiz value twice. Why not once but twice?
