Expected behavior

I am wondering if we can use https://cdn.jsdelivr.net/npm/hexo-theme-next@8.2.1/source/js/utils.min.js (ends with .min.js) instead of https://cdn.jsdelivr.net/npm/hexo-theme-next@8.2.1/source/js/utils.js (ends with .js). The minified package is smaller than the original one.

Something like:

if (url.endsWith('.js') && ! url.endsWith(".min.js")) {
  url = url.slice(0,-3) + ".min.js";
}

Actual behavior

• Links to demo site with this feature: N/A
• Links to repository or source code of the blog: N/A

Currently, all scripts from jsdelivr are not minified.

Steps to reproduce the behavior

1. N/A
2. N/A
3. N/A
