You have to change <script src="script.js"> to <script> . 您必须将<script src="script.js">更改为<script> 。
Alternatively you can keep it this way and create a script.js file and copy paste all the code you have inside the <script> tag to the file. 另外，您可以保持这种方式，并创建一个script.js文件，然后将<script>标记内的所有代码复制粘贴到该文件中。 This file need to be in the same folder as your index.html file. 该文件必须与index.html文件位于同一文件夹中。

Firstly, make the <script src="index.js"></script> seperate from the code in the head, also unless if you have a seperate javascript file you dont need the src part at all, and secondly the first console.log outputs it before definition, creating an error. 首先，使<script src="index.js"></script>与头部的代码分开，也除非您有单独的javascript文件，否则根本不需要src部分，其次是第一个控制台。日志在定义之前将其输出，从而产生错误。 I hope this helped 希望这对您有所帮助

If you are putting your JS code in html just add them between <script></script> tag. 如果要将JS代码放入html中，只需将它们添加在<script></script>标记之间。
You do not need to add src for script unless your JavaScript code is coming from a separate script file. 除非您的JavaScript代码来自单独的脚本文件，否则无需为脚本添加src 。
The src attribute specifies the URL of an external script file .
If you want to run the same JavaScript on several pages in a web site, you should create an external JavaScript file, instead of writing the same script over and over again.
<script>tag<script>标记中的src属性引用该文件。
. 。
As per the instructions that you are following : "Link the JavaScript page to the HTML page." 按照您所遵循的说明： “将JavaScript页面链接到HTML页面。”
- Create another file "index.js" in your project directory. 在您的项目目录中创建另一个文件“ index.js”。
Move your js code into the
index.jsfile in your project directory and then use :将您的js代码移到项目目录中的index.js文件中，然后使用：<script src="index.js"></script>in your HTML.HTML中的<script src="index.js"></script>。
