这次给大家带来diff的对象是虚拟dom，使用diff虚拟dom对象的注意事项有哪些，下面就是实战案例，一起来看一下。

虚拟dom

diff算法首先要明确一个概念就是diff的对象是虚拟dom，更新真实dom则是diff算法的结果

Vnode基类

 constructor (
  。。。
 ) {
  this.tag = tag
  this.data = data
  this.children = children
  this.text = text
  this.elm = elm
  this.ns = undefined
  this.context = context
  this.fnContext = undefined
  this.fnOptions = undefined
  this.fnScopeId = undefined
  this.key = data && data.key
  this.componentOptions = componentOptions
  this.componentInstance = undefined
  this.parent = undefined
  this.raw = false
  this.isStatic = false
  this.isRootInsert = true
  this.isComment = false
  this.isCloned = false
  this.isOnce = false
  this.asyncFactory = asyncFactory
  this.asyncMeta = undefined
  this.isAsyncPlaceholder = false
 }
