I am studying Asp.net core 3.1, and now I want to import a js external file to an Html page, inside of <script> tag I have an asp-append-version="true" attribute, I think this is an attribute of Asp.net core, I don't know why we should use it?
<script src="~/js/site.js" asp-append-version="true"></script>
Thank you for any explanation!!!!

Oh, this is a new function very helpful in Asp.net core. If you add asp-append-version="true" attribute to <script> or <style> tag Asp.net core will auto add version to end of URL path. This version always unique and change after each deploying a new code version.
It always creates a new URL to help browser auto clear cache for this file and always update the latest code.
Your code :
<script src="~/js/site.js" asp-append-version="true"></script>Code after compile and display response to the client:
<script src="/js/site.js?v=Ynfdc1vuMNOWZfqTj4N3SPcebazoGXiIPgtfE-b2TO4"></script>
