import React from 'react'

import styled from '@emotion/styled'

const Something: React.FC = () => {
  const { ... } = useHooksForSomething()
  
  return <Container>Hello, World</Container>
}

// 로직(Custom Hooks)
function useHooksForSomething() {
  // ...
}

// 스타일(CSS-in-JS)
const Container = styled.div`
  background-color: red;

const Something: React.ExoticComponent<Props> = (props) => {
  return (
    <div>
      <h1>{props.article.title}</h1>
