字节面经-前端-一面

1、自我介绍
2、围绕项目展开问了一些
3、代码输出题
const first = () =>
new Promise((resolve, reject) => {
    console.log(3)
let p = new Promise((resolve, reject) => {
      console.log(7)
setTimeout(() => {
        console.log(5)
        resolve(6)
      }, 0)
      resolve(1)
    })
    resolve(2)
p.then((arg) => {
      console.log(arg)
    })
  })
first().then((arg) => {
  console.log(arg)
})
console.log(4)
4、两个有序数组排序
5、如何更快的让用户看到渲染的页面
