promise 调度的问题

Question

var p3 = new Promise( (resolve, reject) => {    resolve('B')})var p1 = new Promise( (resolve, reject) => {    resolve(p3)})p2 = new Promise( (resolve, reject) => {    resolve('A')})p1.then(v => console.log(v))p2.then(v => console.log(v))node 与 浏览器运行不一致。 正常的理解 p1 内部 resolve 了一个 promise 不是同步的的 所以明显要p2晚一点。
