Not sure what you mean by "in between the script" and "outside the script", but the image you posted is of "inline" javascript. Similarly to the way you can write CSS in a <style></style> tag or attach it from an external file, you can write javascript directly in the HTML by enclosing it in a <script></script> tag, or you can write it in an external file and link it in a <script> tag, eg

<script type="text/javascript" src="script.js"></script>

and put the javascript code in the script.js file.

Usually if you want to dynamically generate HTML (e.g. different HTML based on some internal state). Or in this case maybe to give some more context to the date value.

In trivial applications such as this, there isn’t any reason to separate your JavaScript into its own file.

 

However, once you start to work with more advanced applications, particularly where the design follows MVC principles or uses frameworks, it becomes unjustifiable (though not strictly necessary in most cases) to embed all of your JavaScript in your HTML.

 

Another case is where you’re writing TypeScript, which is a superset of JavaScript and cannot be directly embedded into HTML.
