<p>上述代码申明了<code>microTimerFunc</code> 和 <code>macrotimerFunc</code> 两个变量，分别对应的<code>micro task</code> 和<code>macro task</code>的函数，对于<code>macro task</code>的实现，优先检测是否支持原生的<code>setImmediate</code>，不支持的话再检测是否支持原生<code>MessageChannel</code>，不如果支持的话则降级为<code>setTimeout 0</code>；对于<code>micro task</code>的实现，则检测是否支持原生的<code>Promise</code>，不支持的话则直接指向<code>macro task</code>的实现。</p>
<p><code>nextTick</code>方法的逻辑是，把传入的<code>cb</code>压入<code>callbacks</code>数组，最后根据<code>useMacroTask</code>来判断执行<code>macroTimerFunc</code>或者<code>microTimerFunc</code>，它们都会在下一个<code>tick</code>执行<code>flushCallbacks</code>，<code>flushCallbacks</code>的逻辑就是对<code>callbacks</code>进行便利，再执行相应的回调函数。</p>
<p>这里使用 <code>callbacks</code> 而不是直接在 <code>nextTick</code> 中执行回调函数的原因是保证在同一个 tick 内多次执行 <code>nextTick</code>，不会开启多个异步任务，而把这些异步任务都压成一个同步任务，在下一个 tick 执行完毕。</p>
<p>当 <code>nextTick</code> 不传 <code>cb</code> 参数的时候，提供一个 Promise 化的调用，比如：</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">nextTick().then(<span class="function"><span class="params">()</span> =></span> {})</span><br></pre></td></tr></table></figure>
<p>Vue.js 提供了 2 种调用 <code>nextTick</code> 的方式，一种是全局 API <code>Vue.nextTick</code>，一种是实例上的方法 <code>vm.$nextTick</code>，无论使用哪一种，最后都是调用上面实现的 <code>nextTick</code> 方法。</p>

<h1 id="Vue依赖收集"><a href="#Vue依赖收集" class="headerlink" title="Vue依赖收集"></a>Vue依赖收集</h1><p>在初始化<code>Vue</code>的每个组件时，会对组件的<code>data</code>进行初始化，就会将由普通对象变成响应式对象，在这个过程中便会进行依赖收集的相关逻辑，如下所示:</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><span class="line"><span class="function"><span class="keyword">function</span> <span class="title">defieneReactive</span> (<span class="params">obj, key, val</span>)</span>{</span><br><span class="line"> <span class="keyword">const</span> dep = <span class="keyword">new</span> Dep();</span><br><span class="line"> ...</span><br><span class="line"> <span class="built_in">Object</span>.defineProperty(obj, key, {</span><br><span class="line"> ...</span><br><span class="line"> <span class="keyword">get</span>: function reactiveGetter () {</span><br><span class="line"> <span class="keyword">if</span>(Dep.target){</span><br><span class="line"> dep.depend();</span><br><span class="line"> ...</span><br><span class="line"> }</span><br><span class="line"> <span class="keyword">return</span> val</span><br><span class="line"> }</span><br><span class="line"> ...</span><br><span class="line"> })</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>以上只保留了关键代码，主要就是 <code>const dep = new Dep()</code>实例化一个<code>Dep</code>的实例，然后在<code>get</code>函数中通过<code>dep.depend()</code>进行依赖收集。</p>
<h3 id="Dep"><a href="#Dep" class="headerlink" title="Dep"></a>Dep</h3><p><code>Dep</code>是整个依赖收集的核心，关键代码如下：</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br><span class="line">16</span><br><span class="line">17</span><br><span class="line">18</span><br><span class="line">19</span><br><span class="line">20</span><br><span class="line">21</span><br><span class="line">22</span><br><span class="line">23</span><br><span class="line">24</span><br><span class="line">25</span><br><span class="line">26</span><br></pre></td><td class="code"><pre><span class="line"><span class="class"><span class="keyword">class</span> <span class="title">Dep</span> </span>{</span><br><span class="line"> <span class="keyword">static</span> target;</span><br><span class="line"> subs;</span><br><span class="line"> </span><br><span class="line"> <span class="keyword">constructor</span> () {</span><br><span class="line"> ...</span><br><span class="line"> <span class="keyword">this</span>.subs = [];</span><br><span class="line"> }</span><br><span class="line"> addSub (sub) {</span><br><span class="line"> <span class="keyword">this</span>.subs.push(sub)</span><br><span class="line"> }</span><br><span class="line"> removeSub (sub) {</span><br><span class="line"> remove(<span class="keyword">this</span>.sub, sub)</span><br><span class="line"> }</span><br><span class="line"> depend () {</span><br><span class="line"> <span class="keyword">if</span>(Dep.target){</span><br><span class="line"> Dep.target.addDep(<span class="keyword">this</span>)</span><br><span class="line"> }</span><br><span class="line"> }</span><br><span class="line"> notify () {</span><br><span class="line"> <span class="keyword">const</span> subs = <span class="keyword">this</span>.subds.slice();</span><br><span class="line"> <span class="keyword">for</span>(<span class="keyword">let</span> i = <span class="number">0</span>;i < subs.length; i++){</span><br><span class="line"> subs[i].update()</span><br><span class="line"> }</span><br><span class="line"> }</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p><code>Dep</code>是一个<code>class</code>，其中有一个关键的静态属性<code>static</code>，它指向了一个全局唯一<code>Watcher</code>，保证了同一时间全局只有一个<code>watcher</code>被计算，另一个属性<code>subs</code>则是一个<code>Watcher</code>的数组，所以<code>Dep</code>实际上就是对<code>Watcher</code>的管理，再看看<code>Watcher</code>的相关代码：</p>
<h3 id="Watcher"><a href="#Watcher" class="headerlink" title="Watcher"></a>Watcher</h3><figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br><span class="line">16</span><br><span class="line">17</span><br><span class="line">18</span><br><span class="line">19</span><br><span class="line">20</span><br><span class="line">21</span><br><span class="line">22</span><br><span class="line">23</span><br></pre></td><td class="code"><pre><span class="line"><span class="class"><span class="keyword">class</span> <span class="title">Watcher</span> </span>{</span><br><span class="line"> getter;</span><br><span class="line"> ...</span><br><span class="line"> <span class="keyword">constructor</span> (vm, expression){</span><br><span class="line"> ...</span><br><span class="line"> <span class="keyword">this</span>.getter = expression;</span><br><span class="line"> <span class="keyword">this</span>.get();</span><br><span class="line"> }</span><br><span class="line"> <span class="keyword">get</span> () {</span><br><span class="line"> pushTarget(<span class="keyword">this</span>);</span><br><span class="line"> value = <span class="keyword">this</span>.getter.call(vm, vm)</span><br><span class="line"> ...</span><br><span class="line"> <span class="keyword">return</span> value</span><br><span class="line"> }</span><br><span class="line"> addDep (dep){</span><br><span class="line"> ...</span><br><span class="line"> dep.addSub(<span class="keyword">this</span>)</span><br><span class="line"> }</span><br><span class="line"> ...</span><br><span class="line">}</span><br><span class="line"><span class="function"><span class="keyword">function</span> <span class="title">pushTarget</span> (<span class="params">_target</span>) </span>{</span><br><span class="line"> Dep.target = _target</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p><code>Watcher</code>是一个<code>class</code>，它定义了一些方法，其中和依赖收集相关的主要有<code>get</code>、<code>addDep</code>等。</p>
<h3 id="过程"><a href="#过程" class="headerlink" title="过程"></a>过程</h3><p>在实例化<code>Vue</code>时，依赖收集的相关过程如下：</p>
<p>1.初始化状态<code>initState</code>，这中间便会通过<code>defineReactive</code>将数据变成响应式对象，其中的<code>gette r</code>部分便是用来依赖收集的。</p>
<p>2.初始化最终会走<code>mount</code>过程，其中会实例化<code>Watcher</code>，进入<code>Watcher</code>中，便会执行<code>this.get()</code>方法，</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">updateComponent = <span class="function"><span class="params">()</span> =></span> {</span><br><span class="line"> vm._update(vm._render())</span><br><span class="line">}</span><br><span class="line"><span class="keyword">new</span> Watcher(vm, updateComponent)</span><br></pre></td></tr></table></figure>
<p><code>get</code>方法中的<code>pushTarget</code>实际上就是把<code>Dep.target</code>赋值为当前的<code>watcher</code>。</p>
<p><code>this.getter.call(vm, vm)</code>，这里的<code>getter</code>会执行<code>vm._render()</code>方法，在这个过程中便会 触发数据对象的<code>getter</code>。</p>
<p>那么每个对象值的 getter 都持有一个 <code>dep</code>，在触发 getter 的时候会调用 <code>dep.depend()</code> 方法，也就会执行 <code>Dep.target.addDep(this)</code>。</p>
<p>刚才 <code>Dep.target</code> 已经被赋值为 <code>watcher</code>，于是便会执行 <code>addDep</code> 方法，然后走到<code>dep.addSub()</code>方法，便将当前的 <code>watcher</code> 订阅到这个数据持有的 <code>dep</code> 的 <code>subs</code> 中，这个目的是为后续数据变化时候能通知到哪些 <code>subs</code> 做准备。</p>
<p>所以在 <code>vm._render()</code> 过程中，会触发所有数据的 getter，这样便已经完成了一个依赖收集的过程。</p>

<h3 id="Http2特性，Http2-怎么确保文件同时传输不会报错"><a href="#Http2特性，Http2-怎么确保文件同时传输不会报错" class="headerlink" title="Http2特性，Http2 怎么确保文件同时传输不会报错?"></a>Http2特性，Http2 怎么确保文件同时传输不会报错?</h3><p>1.二进制传输：</p>
<p>在之前的<code>http</code>中，是通过文本传输的，在<code>http2</code>中所有的传输数据都会被分割，并采用二进制格式编码。</p>
<p>2.多路复用：</p>
<p>在说多路复用之前，先说一下在http2中有两个概念，分别是<code>stream(流)</code>和<code>frame(帧)</code>，<code>frame</code>是最小的单位，每个<code>frame</code>会有 <code>Stream Identifier</code> 来标示它是属于哪个<code>stream</code>的。</p>
<p>在<code>http1.x</code>情况下，每个<code>http</code>请求都会建立一个<code>tcp</code>连接，也就意味着每个请求都要进行三次握手，这会造成时间和资源的浪费，而且浏览器会限制同一域名下并发请求的个数，当请求很多资源时，队头阻塞会导致在达到最大请求数量时，剩余的资源要等待其他资源请求完成才能发起请求(这里可以引申一下针对此种情况的优化手段，就是把不同资源放在不同域名下，以此来突破浏览器最大并发数的限制)。</p>
<p>在<code>http2</code>的情况下，所有的请求都会共用一个<code>tcp</code>连接，就可以传输所有的请求数据。这就解决了浏览器同一域名请求数量的问题，也解决了每开一个<code>tcp</code>连接都会造成的资源时间浪费。</p>
<p>但是同一个<code>tcp</code>连接下多个<code>http</code>请求，如何保证传输不出错呢？这就要用到开始提到的两个概念了，多路复用，就是在一个<code>tcp</code>连接中可以存在多个<code>stream</code>，也就是多个请求，每个<code>stream</code>又包含了多个<code>frame</code>，通过<code>Stream Identifier</code> 就可以识别出每个<code>frame</code>分别对应的<code>stream</code>，当<code>frame</code>到达服务端之后，就可以根据<code>Stream Identifier</code> 来重新组合得到完整的请求了，这就在提高传输性能的同时保证了传输的正确性。</p>
<p>3.<code>Header</code>压缩</p>
<p><code>http1.x</code>中，使用文本的形式传输<code>header</code>每次请求都会带上，这些基本上都是不变的，如果再加上<code>cookie</code>的话也是不小的浪费。</p>
<p><code>http2</code>中，使用了<code>HPACK</code>压缩格式对<code>header</code>进行了编码，减少了<code>header</code>的大小，大概原理就是在服务端和客户端共同维护一个静态字典，用于记录出现过的<code>header</code>，后面在传输过程中发送端直接传输已经记录过的键名，接收端就可以通过键名找到对应的值。</p>
<p>4.服务端<code>push</code></p>
<p>在<code>http2</code>中，服务端可以在客户端的某个请求后，根据这个请求，主动推送其他的资源。</p>
<p>比如一个<code>html</code>页面中还带上可一个<code>css</code>和<code>js</code>的资源请求，<code>http1.x</code>时，要发送三次请求，在<code>http2</code>中，不用请求三次，服务器发现<code>html</code>中包含了<code>css</code>和<code>js</code>资源，便会将三个资源都返回给客户端，这样只需要一次通信，就可以获得全部资源。</p>

<p><code>HTTP/2.0</code>支持多路复用，这是<code>HTTP/1.X</code>持久连接的升级版。多路复用，就是在一个 <code>TCP</code> 连接中可以存在多条流，也就是可以发送多个请求，服务端则可以通过帧中的标识知道该帧属于哪个流（即请求），通过重新排序还原请求。多路复用允许并发的发起多个请求，每个请求及该请求的响应不需要等待其他的请求或响应，避免了线头阻塞问题。这样某个请求任务耗时严重，不会影响到其它连接的正常执行,极大的提高传输性能。</p>

<h3 id="webpack多入口打包："><a href="#webpack多入口打包：" class="headerlink" title="webpack多入口打包："></a>webpack多入口打包：</h3><p>基本思路就是每个⻚⾯对应⼀个 entry，⼀个 html-webpack-plugin，但是这样的缺点就是每次新增或删除⻚⾯需要改 webpack 配置，如下所示：</p>

<p>所以便有了以下的通用方案：</p>
<p>利⽤ glob.sync 动态获取 entry 和设置 html-webpack-plugin 数量（不过要求src里面的入口必须按照’./src/*/index.js’来配置，比如’./src/index/index.js’ 或者 ‘./src/serach/index.js’，并且在该目录下放入相应的html模板，比如’./src/index/index.html’ 或者 ‘./src/serach/index.html’），如下所示：</p>

<h3 id="loader："><a href="#loader：" class="headerlink" title="loader："></a>loader：</h3><p>Loader 本身仅仅只是一个函数，接收模块代码的内容，然后返回代码内容转化后的结果，并且一个文件还可以链式的经过多个loader转化(比如scss-loader => css-loader => style-loader)。<br>一个 Loader 的职责是单一的，只需要完成一种转化。 如果一个源文件需要经历多步转化才能正常使用，就通过多个 Loader 去转化。 在调用多个 Loader 去转化一个文件时，每个 Loader 会链式的顺序执行， 第一个 Loader 将会拿到需处理的原内容，上一个 Loader 处理后的结果会传给下一个接着处理，最后的 Loader 将处理后的最终结果返回给 Webpack。</p>
<p>以下是一个最简单的loader例子</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span class="line"><span class="built_in">module</span>.exports = <span class="function"><span class="keyword">function</span>(<span class="params">source</span>) </span>{</span><br><span class="line"> <span class="comment">// source 为 compiler 传递给 Loader 的一个文件的原内容</span></span><br><span class="line"> <span class="comment">// 该函数需要返回处理后的内容，这里简单起见，直接把原内容返回了，相当于该 Loader 没有做任何转换</span></span><br><span class="line"> <span class="keyword">return</span> source;</span><br><span class="line">};</span><br></pre></td></tr></table></figure>
<h3 id="plugin："><a href="#plugin：" class="headerlink" title="plugin："></a>plugin：</h3><p>plugin 的实现可以是一个类，使用时传入相关配置来创建一个实例，然后放到配置的 <code>plugins</code> 字段中，而 plugin 实例中最重要的方法是 <code>apply</code>，该方法在 webpack compiler 安装插件时会被调用一次，<code>apply</code> 接收 webpack compiler 对象实例的引用，你可以在 compiler 对象实例上注册各种事件钩子函数，来影响 webpack 的所有构建流程，以便完成更多其他的构建任务。</p>
<p>一下 是一个最简单的plugin例子：</p>

<p>Webpack 启动后，在读取配置的过程中会先执行 new BasicPlugin(options) 初始化一个 BasicPlugin 获得其实例。 在初始化 compiler 对象后，再调用 basicPlugin.apply(compiler) 给插件实例传入 compiler 对象。 插件实例在获取到 compiler 对象后，就可以通过 compiler.plugin(事件名称, 回调函数) 监听到 Webpack 广播出来的事件。 并且可以通过 compiler 对象去操作 Webpack。</p>
<p>在开发 Plugin 最主要的就是理解 compiler 和 compilation，它们是 Plugin 和 Webpack 之间的桥梁。这两者提供的各种 hooks 和 api，则是开发 plugin 所必不可少的材料，通过 compiler 和 compilation 的生命周期 hooks，也可以更好地深入了解 webpack 的整个构建工作是如何进行的。</p>

<p>ES Module 与 CommonJS 有以下几个区别</p>
<ul>
<li><p>CommonJS 在导出时都是值拷贝，就算导出的值变了，导入的值也不会改变，所以如果想更新值，必须重新导入一次。但是 ES Module 采用实时绑定的方式，导入导出的值都指向同一个内存地址，所以导入值会跟随导出值变化</p>
</li>
<li><p>ES Module 会编译成 <code>require/exports</code> 来执行的</p>
</li>
<li><p>CommonJS 模块是运行时加载，ES6 模块是编译时输出接口</p>
</li>
<li><p>CommonJS 加载的是整个模块，即将所有的接口全部加载进来，ES6 可以单独加载其中的某个方法</p>
</li>
</ul>

<h3 id="自己实现new"><a href="#自己实现new" class="headerlink" title="自己实现new"></a>自己实现new</h3><p>在Javascript中，使用new关键字创建一个对象时，好像是基于类的继承，然而真实的情况却是基于原型继承的。来看看new关键字到底做了什么：</p>
<ul>
<li>1.创建一个对象</li>
<li>2.使这个对象的<code>__proto__</code>指向构造函数的<code>prototype</code></li>
<li>3.执行构造函数，将创建的空对象赋值给构造函数内部的<code>this</code></li>
<li>4.根据构造函数的逻辑，返回第一步创建的对象或者构造函数内部显示返回值</li>
</ul>
<p>下面模拟实现<code>new</code>：</p>

<h3 id="JavaScript类型及其判断"><a href="#JavaScript类型及其判断" class="headerlink" title="JavaScript类型及其判断"></a>JavaScript类型及其判断</h3><p>目前JavaScript具有7种数据类型，分别是：</p>
<p><code>null</code>,<code>undefined</code>,<code>number</code>,<code>string</code>,<code>boolean</code>,<code>symbol</code>以及<code>object</code>。</p>
<p>前五种是原始类型，<code>symbol</code>是新增的比较特殊也属于原始类型，<code>object</code>是引用类型(<code>object</code>又具体包含了<code>function</code>,<code>date</code>,<code>array</code>等)。</p>
<p>对于这些类型的判断，基本上有一下常用的方法：</p>
<ul>
<li><code>typeof</code></li>
<li><code>instanceof</code></li>
<li><code>Object.prototype.toString</code></li>
<li><code>constructor</code></li>
</ul>

<p>闭包是Javascript里面最基本也是最重要的知识点之一，说到闭包，又要涉及到作用域、作用域链、执行上下文(执行环境)、甚至内存管理等其他知识点。</p>
<h3 id="作用域"><a href="#作用域" class="headerlink" title="作用域"></a>作用域</h3><p>通俗点说，<strong>作用域为可访问变量，对象，函数的集合</strong>，或者说作用域作为一套规则，该规则<strong>用于确定在特定场景下如何查找变量</strong>。在ES6出现之前，JavaScript只有函数作用域和全局作用域。</p>
