【React】 props を使ってみる

Last updated at Posted at 2020-11-28

はじめに

React を習得するまでの軌跡をメモっていく備忘録的な記事です。

props を使ってみる

index.js
import React from 'react';
import ReactDOM from 'react-dom';

const User = (props) => {
  return (
    <p>私の名前は{props.name}です。</p>
  )
};

ReactDOM.render(
    <User name={'太郎'} />,
  document.getElementById('root')
);

まとめ

  • コンポーネントの引数に props と入れる。

  • コンポーネントの中では props.hoge という形で props の値が取り出せる。

  • コンポーネントへの渡し方は \<Hoge hoge={値} />
