外什么要做这个插件

• 很多代码编辑预览的网站，例如 jsfiddle，但很多都不能离线使用
• 支持 js 程度不全，例如 vue 的 jsx 但很多不支持
• 复制黏贴测试代码来回切换太麻烦

功能介绍

Async

;(async () => {
  const a = await 'Async Await'
  console.log(a)
})()
// Async Await

Class Properties

class A {
  s = 'Class Properties'
	test() {
    console.log(this.s)
  }
}

(new A()).test()
// Class Properties

Object Rest Spread

const s = [1,2]
const b = [3, ...s]
console.log(b)
// 3,1,2

Decorators

function log(target, name, descriptor) {
  const original = descriptor.value
  if (typeof original === 'function') {
    descriptor.value = function(...args) {
      console.log(`Arguments: ${args}`)
      try {
        const result = original.apply(this, args)
        console.log(`Result: ${result}`)
        return result
      } catch (e) {
        console.log(`Error: ${e}`)
        throw e
      }
    }
  }
  return descriptor
}

class Example {
    @log
    sum(a, b) {
        return a + b
    }
}

const e = new Example()
e.sum(1, 2)
// Arguments: 1,2
// Result: 3
