vue v2.5.0源码-双向数据绑定

把option.data转变为vm._data的可观察对象

new Vue => this._init() => initState(vm) => initData(vm) => observe(data) => new Observer(data) => walk(data) => defineReactive(obj, key, value) => dep.depend() =>  

watcher.addDep(dep) => watcher.newDeps.push(dep),dep.addSub(watcher) => dep.subs.push(watcher) =>dep.notify()

建立双向数据绑定

vm.$mount => mountComponent => new Watcher(vm, updateComponent) => updateComponent => render => getter =>建立双向数据绑定
