为哈 a1 在 b3 后面
function runCode() {
Promise.resolve()
.then(res => Promise.resolve())
.then(res => console.log('a1'))
.then(res => console.log('a2'))
Promise.resolve()
.then(res => console.log('b1'))
.then(res => console.log('b2'))
.then(res => console.log('b3'))
.then(res => console.log('b4'))
.then(res => console.log('b5'))
.then(res => console.log('b6'))
}
