更好的在 vue-devtools 中调试 vue bus

import {isObject} from './helper'

/**
 * 私有注释对象

export const _comments = Object.create(null)

/**
 * 获取最终的注释
 * @param {string} paths 路径
 * @return {string} 注释

  }

  let comment = ''
  let current = _comments
  let i = 0
  while (++i) {

    if (i === paths.length) break
  }

  return isObject(current) ? current._comment : current

export function aa () {

window.aa = aa
