본문

import { useState, useEffect } from "react";

import { useParams } from "react-router-dom";

function Detail() {

const { id } = useParams();

const [movies, setMovies] = useState([]);

const getMovie = async () => {

const json = await (

await fetch(`https://yts.mx/api/v2/movie_details.json?movie_id=${id}`)

).json()

setMovies(json.data.movie);

};

useEffect(() => {

getMovie();

}, []);

return (

<div>

{movies && movies.map((movie) => (

<h2>{movie.title}</h2>

<p>{movie.summary}</p>

</div>

))}

</div>

);

}

export default Detail;

movies를 분명 useState를 이용하여 배열로 만들어줬는데도 map is not a function 에러가 뜨네요,,,, 뭐가 문제일까요?ㅜㅜㅜㅜ

https://yts.mx/api/v2/movie_details.json?movie_id=1

여기로 접근해보니

json.data.movie 자체가 객체네요
