According to Yahoo performance team the <script> should be placed at the bottom of the page. 根据Yahoo绩效小组的说法， <script>应该放在页面底部。 But the problem caused by scripts is that they block parallel downloads which might slow the page. 但是由脚本引起的问题是它们阻止并行下载，这可能会使页面变慢。
Another suggestion is to use async and defer . 另一个建议是使用async和defer 。 The async and defer HTML attributes let you control when and how JavaScript files are downloaded and executed. async和defer HTML属性使您可以控制何时以及如何下载和执行JavaScript文件。 Using these attributes, you can reduce the amount of time users spend waiting on JavaScript without having to change your scripts. 使用这些属性，可以减少用户等待JavaScript所花费的时间，而不必更改脚本。
