Slice 기능 활용

import PropTypes from "prop-types";
import { Link } from "react-router-dom";

function Movie({ id, coverImg, title, summary, genres }) {
  return (
    <div>
      <img src={coverImg} alt={title} />
      <h2>{title}</h2>
      다.
      <h2>
        <Link to={`/movie/${id}`}>{title}</Link>
      </h2>
      <p>{summary.length > 235 ? `${summary.slice(0, 235)}...` : summary}</p>
      //0부터 235까지 잘라준다
    </div>
  );
}
Movie.propTypes = {
  id: PropTypes.number.isRequired,
  coverImg: PropTypes.string.isRequired,
  title: PropTypes.string.isRequired,
  summary: PropTypes.string.isRequired,
};
export default Movie;
