Jsdelivr

Jsdelivr is a tool that allows programmers to service WordPress plugins or any GitHub file via CDN. This tool allows you to combine multiple files in one URL to get a reduced version of JS and CSS.

This technology (CDN) itself is widely used for website developers to keep the website stable and active when problems occur.

CDN is a network of servers that are connected together with the aim of delivering content quickly and reliably, also offering security using cache technology.
