  1. new changes (updates) applied in virtual DOM
  2. Virtual DOM copmared with Real DOM
  3. only changed items applied to Real DOM => EFFICIENT!
• Required:
  1. Node JS
  2. Yarn (quicker than NPM)
  3. VS CODE (or use online IDE (code sandbox))
  4. git

npm create-react-app APPNAME
yarn start (또는 npm start)

• Componenets (Function형)

  import React from 'react' #
