The getbootstrap.com docs include jsDelivr, stating:
Skip the download with jsDelivr to deliver cached version of Bootstrap’s compiled CSS and JS to your project.
According to https://www.jsdelivr.com/about :
jsDelivr is a public, open-source CDN (Content Delivery Network) developed by Dmitriy Akulov and Prospect One, focused on performance, reliability, and security. It is free to use for everyone, with no bandwidth limits.
I don't really understand what this means or how it compares to say, simply downloading with npm
. Can anyone explain?
