es6解构赋值

解构赋值
如对象解构

 // es6 
 const electron = require('electron')
 const { app, BrowserWindow } = electron
 let win
 app.on('ready', () => {
   win = new BrowserWindow()
   win.loadURL('https://github.com')
 })
 
 // 相当于es5

 const electron = require('electron')
 const app = electron.app
 const BrowserWindow = electron.BrowserWindow
 let win
 app.on('ready', () => {
   win = new BrowserWindow()
   win.loadURL('https://github.com')
 })

数组的解构

// es5 Dirty
const locale = 'zh-CN';
const splitLocale = locale.split('-');
const language = splitLocale[0];
const country = splitLocale[1];
// es6 Clean
const [language, country] = locale.split('-');
