react新版api

// index.tsx
import React from 'react'
import ReactDOM from 'react-dom'

console.log('Hello from tsx!')
ReactDOM.render(<p>Hello</p>, document.getElementById('root'))

react-dom.development.js:86 Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot

// index.tsx
import React from 'react'
import { createRoot } from 'react-dom/client'

console.log('Hello from tsx!')
createRoot(document.getElementById('root')).render(<p>Hello</p>)
