```js
|
||||
try {
|
||||
(async function() { a().b().c() })()
|
||||
} catch (e) {
|
||||
console.log(`执行出错:${e.message}`)
|
||||
}
|
||||
```
|
||||
|
||||
这道题目主要三个考点:
|
||||
|
||||
1. 执行一个没有定义的函数会发生什么
|
||||
2. 在 `async` 内部发生报错会发生什么
|
||||
3. `try catch` 只能捕获同步代码的异常
|
||||
|
||||
因此答案就明了了。
|
||||
|
||||
因为我们执行了一个未定义的函数,所以会报错 `a is not defind`,又因为是在 `async` 中,所以报错信息会显示 `in promise`。最后 `try cathch` 只能捕获同步代码的抛错,因为是 `async`,所以走不到 `catch` 里面。
|
||||
|
||||
如果我们把代码这样改一下就可以了:
|
||||
|
||||
```js
|
||||
try {
|
||||
await (async function() { a().b().c() })()
|
||||
} catch (e) {
|
||||
console.log(`执行出错:${e.message}`)
|
||||
}
|
||||
```
|
||||
|
||||
另外说个小知识点,最新的 Chrome 已经支持在全局作用域下使用 `await` 了。

这道题目基础不好的同学容易答错,很容易以为 `async` 的函数内部代码就是异步的,实际都还是同步的,把代码改成这样大家就明白了:
|
||||
|
||||
```js
|
||||
function a() {
|
||||
return new Promise(function(resolve, reject) {
|
||||
a += 1
|
||||
console.log('inner', a)
|
||||
throw new Error('123')
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
另外发现还有同学疑问为什么 `throw` 出去的错误被 `promise catch` 住了,这个我们直接看标准:

页面上有三个按钮,分别为 A、B、C,点击各个按钮都会发送异步请求且互不影响,每次请求回来的数据都为按钮的名字。
|
||||
|
||||
请实现当用户依次点击 A、B、C、A、C、B 的时候,最终获取的数据为 ABCACB。
|
||||
|
||||
这道题目主要两个考点:
|
||||
|
||||
1. 请求不能阻塞,但是输出可以阻塞。比如说 B 请求需要耗时 3 秒,其他请求耗时 1 秒,那么当用户点击 BAC 时,三个请求都应该发起,但是因为 B 请求回来的慢,所以得等着输出结果。
|
||||
2. 如何实现一个队列?
|
||||
|
||||
其实我们无需自己去构建一个队列,直接利用 `promise.then` 方法就能实现队列的效果了。

异步请求通过 `Promise.all` 处理,怎么让其中失败的所有请求重试。
|
||||
|
||||
```js
|
||||
Promise.all([A, B, C, D])
|
||||
// 4 个请求完成后发现 AD 请求失败了,如果让 AD 请求重试
|
||||
```
|
||||
|
||||
这个题目其实很简单,因为 `Promise.all` 中一个 `promise` 挂了就挂了,所以我们直接在接口上处理 `catch` 就行了。
|
||||
|
||||
看了些答案,结果是对的,但是处理方式是错误的。比如说在 `resolve` 中去判断是否要重试。一般我们业务中请求都是封装过的函数,出现错误肯定直接 `reject` 了,不可能 `resolve` 出来。

这道题目其实就是让大家实现一个 lodash 里的函数,这边我们需要注意的一个点是不能更改原数组,虽然题目没有提到,但是我们得想到这个。
|
||||
|
||||
笔者这里推荐几个答案,分别是不同的写法,难度从低到高吧。
|
||||
|
||||
首先是遍历的写法:
|
||||
|
||||
[答案链接](https://github.com/KieSun/fucking-frontend/issues/8#issuecomment-799053150)
|
||||
|
||||
```js
|
||||
function chunk(arr, num) {
|
||||
if (num === 0) return [];
|
||||
if (Array.isArray(arr) && typeof num === "number") {
|
||||
let result = [];
|
||||
let i = 0;
|
||||
while (i < arr.length) {
|
||||
result.push(arr.slice(i, i + num));
|
||||
i += num;
|
||||
}
|
||||
return result;
|
||||
} else {
|
||||
console.log("params type error");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
我们也可以使用 `reduce` 来解题:
|
||||
|
||||
[答案链接](https://github.com/KieSun/fucking-frontend/issues/8#issuecomment-799021398)
|
||||
|
||||
```js
|
||||
const chunk = (arr, len) => arr.reduce((pre, cur, index) => {
|
||||
if (index % len === 0) {
|
||||
pre.push([cur])
|
||||
return pre
|
||||
}
|
||||
const temp = pre[pre.length - 1]
|
||||
temp && temp.push(cur)
|
||||
return pre
|
||||
}, [])
|
||||
```
|
||||
|
||||
甚至直接优化到一行:
|
||||
|
||||
[答案链接](https://github.com/KieSun/fucking-frontend/issues/8#issuecomment-799344324)
|
||||
|
||||
```js
|
||||
function chunk(arr, size){
|
||||
return Array.from({length: (size = Number.parseInt(size)) ? Math.ceil(arr.length/size) : 0})
|
||||
.map((a,i) => arr.slice(i*size, (i+1)*size))
|
||||
}
|
||||
```

```
|
||||
|
||||
这道题目核心是在考 `this` 的指向,但是还有一些别的坑。
|
||||
|
||||
执行第一次 `fn` 的时候,这时候的 `this` 就是 `window`,但是 `window.length` 并不是指向用 `let` 声明的 `length` 上的,而是「返回当前窗口中包含的框架数量(框架包括frame和iframe两种元素)」,具体可以参考 [文档](https://developer.mozilla.org/zh-CN/docs/Web/API/Window/length)。
|
||||
|
||||
执行第二次 `fn` 的时候,此时 `this` 为 `arguments`,`arguments.length` 为实参的长度,也就是 2。

其实 `a` 为 0 是因为加法运算法,先算左边再算右边,所以会把 0 固定下来。如果我们把题目改成 `await 10 + a` 的话,答案就是 11 了。

## 学习路径
|
||||
|
||||
## 每日大厂原题
|
||||
前端知识点很多这是公认的事情,但是我们确实没必要把所有知识都去学习,那样只会贪多嚼不烂。我们能把核心知识点、热门技术以及工作中需要用到的知识学好就已经能打败大部分前端工程师了,剩下的大家可以自行选择学习内容。
|
||||
|
||||
欢迎大家提供面试题,发送题目至邮箱:zx597813039@gmail.com。
|
||||
接下来的内容笔者会按照优先级高低来排布学习路径的目录,大家只需从上到下顺序学习即可。
|
||||
|
||||
成功采纳后,如果你面试遇到其他问题,笔者可以提供免费解答服务。
|
||||
> 为了保证大家学到的知识是正确的,下文中的文档资料笔者都使用了英文版本。因为在审核资料的过程中笔者发现不少中文文档都存在翻译错误或者过时的情况。
|
||||
|
||||
## 前端核心知识点
|
||||
|
||||
前端核心知识点分为三块,分别为 HTML、CSS、JS,其中最重要的当然是 JS 了。
|
||||
|
||||
如果你还是一位初学者,推荐先自行完整阅读一至二本书后再按照该计划学习。关于书籍笔者推荐以下两本:
|
||||
|
||||
- [JavaScript 高级程序设计(第 4 版)](https://book.douban.com/subject/35175321/)
|
||||
- [JavaScript 忍者秘籍(第 2 版)](https://book.douban.com/subject/30143702/)
|
||||
|
||||
## JS
|
||||
|
||||
### 数据类型
|
||||
|
||||
JS 数据类型分为两大类及八种数据类型,注意别漏了 ES6 新增的 `bigint`。
|
||||
|
||||
- [ ] 文档:
|
||||
- [ ] [JavaScript 数据类型和数据结构](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures)
|
||||
|
||||
### 类型判断
|
||||
|
||||
类型判断有好几种方式,分别为:
|
||||
|
||||
- `typeof`
|
||||
- `instanceof`
|
||||
- `Object.prototype.toString`
|
||||
- `isXXX`,比如 `isArray`
|
||||
|
||||
- [ ] 文档
|
||||
- [ ] [typeof](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/typeof)
|
||||
- [ ] [instanceof](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/instanceof)
|
||||
- [ ] [Object.prototype.toString](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/toString#using_tostring_to_detect_object_class)

|
||||
|
||||
### 类型转换
|
||||
|
||||
类型转换算是 JS 中情况繁杂且容易出错,但是开发中还经常会遇到的知识点。强行全部记忆容易遗忘,推荐记忆及练习开发中的常见情况。
|
||||
|
||||
- [ ] 文档
|
||||
- [ ] [ES 标准](https://tc39.es/ecma262/#sec-abstract-operations)
|
||||
- 标准并不好读,如果读者英文水平欠佳,可以只阅读该小节内的表格内容。
|
||||
- [ ] [双等判断](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Equality)
|
||||

|
||||
|
||||
### this
|
||||
|
||||
`this` 算是不少初学者容易搞混的一个知识点,但是它很重要,务必掌握。
|
||||
|
||||
- [ ] 文档
|
||||

|
||||
|
||||
### 作用域
|
||||
|
||||
作用域是指程序中定义变量的区域,该位置决定了变量的生命周期,也就是变量和函数的可访问范围。

||||
|
||||
### new
|
||||
|
||||
`new` 操作符可以帮助我们构建出一个实例,并且绑定上 `this`。
|
||||

### 变量提升&函数提升
|
||||
|
||||
> 变量提升(Hoisting)被认为是, Javascript中执行上下文 (特别是创建和执行阶段)工作方式的一种认识。例如,从概念的字面意义上说,“变量提升”意味着变量和函数的声明会在物理层面移动到代码的最前面,但这么说并不准确。实际上变量和函数声明在代码里的位置是不会动的,而是在编译阶段被放入内存中。

||||
### 事件循环
|
||||
|
||||
大家都知道 JS 是一门单线程的非阻塞的脚本语言。这也就意味着,代码在执行的任何时候只有一个主线程来处理所有的任务。所以弄懂事件循环机制对我们学习 JS 至关重要。

||||

|
||||
|
||||
### 继承
|
||||
|
||||
继承是面向对象语言(Object-Oriented Language)三大特征之一,在 JS 中也占有非常重要的地位。而想要实现继承有多种方式,它们都有各自的优缺点。
|
||||

|
||||
|
||||
## 跨端框架
|
||||
|
||||
跨端的最主要的含义就是一套代码多端运行,减少重复劳动
|
||||
|
||||
目前看来,国内比较流行的是小程序, H5, App 三端跨的框架, [uniapp](https://github.com/dcloudio/uni-app) 及 [taro](https://github.com/NervJS/taro) 是其中做的比较出彩的两个框架。当然在 taro3.0 之前(以下主要是说小程序),taro 跟 uniapp 都是使用编译时做更多的事情,编译成小程序能够运行的代码。
|
||||
|
||||
而在 taro3.0 之后变成了与 [remax](https://github.com/remaxjs/remax) 相同的思想,在运行时做更多的事情,保证了原框架代码能够完全使用,而不需要为了转换成其他小程序时做兼容。

|
||||
|
||||
## 微前端
|
||||
|
||||
是一种类似于微服务的架构,它将微服务的理念应用于浏览器端,即将单页面前端应用由单一的单体应用转变为多个小型前端应用聚合为一的应用。
|
||||
|
||||
优势:
|
||||
|
||||
- 代码库更小,更内聚、可维护性更高
|
||||
- 松耦合、自治的团队可扩展性更好
|
||||
- 渐进地升级、更新甚至重写部分前端功能成为了可能
|
||||
- 独立开发部署,缩小变更范围,进而降低相关风险

本周精读的第一篇文章是 [Migrating a 150K LOC codebase to Vite and ESBuild](https://dev.to/noriste/migrating-a-150k-loc-codebase-to-vite-and-esbuild-why-part-1-3-2idj),其实这是一个系列文章了,主体内容在第二篇。
|
||||
|
||||
这篇文章主要讲了两块内容:
|
||||
|
||||
1. Webpack 对比 Vite 的一些数据
|
||||
2. 迁移至 Vite 过程中踩得坑
|
||||
|
||||
踩得坑在第二篇文章,如果你近期想试试迁移的话可以读一下,当然其实他并没有写多少踩坑的内容,让我稍微对于他这个迁移那么大项目居然才那么点坑产生怀疑,或者说很多没写上来。
|
||||
|
||||
但是对于数据这块大家还是可以参考参考的,选型时候还是用得上。
|
||||
|
||||
第一块数据是 Webpack 和 Vite 在 `yarn start` 以及 `hmr` 层面的一些对比,可以看到在这两块内容上 Vite 是碾压胜出的,其它两个数据差别不大,可以略过。
|
||||
|
||||
![Y2f6el](https://yck-1254263422.file.myqcloud.com/uPic/Y2f6el.png)
|
||||
|
||||
第二块数据是使用了 esbuild-loader 插件的 Webpack 和 Vite 的数据对比,基本上还是 Vite 胜出,但是可以发现当 Webpack 加上 ESBuild 以后,很多数据相比之前已经有了很大幅度的提升,无非限制于 Webpack 本身的一些打包机制导致了在一些数据上没什么起色。
|
||||
|
||||
![KGiSCa](https://yck-1254263422.file.myqcloud.com/uPic/KGiSCa.png)
|
||||
|
||||
第三块数据是 Build 层面的数据分析,使用了 esbuild-loader 插件的 Webpack 胜出了 Vite。
|
||||
|
||||
![wZrWQX](https://yck-1254263422.file.myqcloud.com/uPic/wZrWQX.png)
|
||||
|
||||
总的来说,从上述这些数据中我们可以看出 Vite 和 ESBuild 对于提效的加成是很大的,轻轻松松提速几倍。
|
||||
|
||||
但是这一切都是美好的,实际你如果要把这套东西在业务中真真正正用起来,会踩到很多坑,目前应该是没有一个大厂能把这套体系在很多业务里跑起来。虽然提效确实挺多,但是迁移的成本也是很大的。
|
||||
|
||||
综合来说,可以自己项目里玩玩,未来这个体系肯定是会普及的,但并不是现在。
|
||||
|
||||
另外对于原理有兴趣的可以看看云谦写的[玩具](https://github.com/sorrycc/toy-vite)。

|
||||
|
||||
一个系列文章,大概讲了讲 15w 行代码从 Webpack 迁移至 Vite 过程中遇到的坑。Vite 这玩意我周末也讲过它的优点,但是它的缺点其实我和一些大厂的大佬也聊过以后发现大家遇到的问题几乎一致。环境的问题(ESM)导致了太多坑的出现,接入一个业务需要花的成本是挺高的。大家可以通过这篇文章来了解具体的问题。

- Node 12 岁生日了
|
||||
- [.at() 进入 Stage 3](https://github.com/tc39/proposal-relative-indexing-method)
|
||||
|
||||
这是个挺不错的新语法。其他有些语言是可以用 `arr[-1]` 来获取数组末尾的元素,但是对于 JS 来说这是实现不了的事情。因为 `[key]` 对于对象来说就是在获取 `key` 对应的值。数组也是对象,对于数组使用 `arr[-1]` 就是在获取 `key` 为 `-1` 的值。由于以上原因,我们想获取末尾元素就得这样写 `arr[arr.length - 1]`,以后有了 `at` 这个方法,我们就可以通过 `arr.at(-1)` 来拿末尾的元素了,另外同样适用类数组、字符串。
|
||||
|
||||
```js
|
||||
// Polyfill
|
||||
function at(n) {
|
||||
// ToInteger() abstract op
|
||||
n = Math.trunc(n) || 0;
|
||||
// Allow negative indexing from the end
|
||||
if(n < 0) n += this.length;
|
||||
// OOB access is guaranteed to return undefined
|
||||
if(n < 0 || n >= this.length) return undefined;
|
||||
// Otherwise, this is just normal property access
|
||||
return this[n];
|
||||
}
|
||||
```

- [居然有比 npm link 更好的调试?](https://mp.weixin.qq.com/s/I4hhrgI3-Y18HD8zw_9g9w)
|
||||
|
||||
用 `npm link` 调试包应该是基本操作了,但是这种方式在某些情况下还是会带来一些不便利性。比如说在使用 React Hooks 的情况下调试与 React 相关的包就会报错。有公共依赖冲突的情况下我们可以 [yalc](https://github.com/wclr/yalc) 这个库来解决问题。它会将包丢到全局,然后我们在项目里添加该依赖即可,公共依赖会从项目的 node_modules 里面拿,其它的就从全局拿,这样就可以解决依赖冲突带来的问题了。
