1. prototype的方法里面的this指的是Vue的实例吗？

需要再看一下prototype

回答是的, 这个相当与给所有的实例增加方法或者属性

2.this.constructor.options 中的this.constructor 需要再看一下高程

vm = new Vue()
vm.constructor === Vue // true
那么这么做的意义是什么呢? 为何要合并constructor中的options?

initData

initData

把options.data返回一个object对象作为vm._data;
如果options.data是function则执行, 并返回; 否则直接返回
