You don't have to download and host jQuery yourself if you don't want to. You can include it in your website from a CDN (Content Delivery Network). Both of the major CDNs – Google and Microsoft – host jQuery.
The advantage of this option is better loading times, and that has two main reasons:
- Most of the internet users have already downloaded jQuery from either Google or Microsoft servers when visiting another site. That means that the next time it's loaded from cache, which makes it faster.
- A CDN usually detects which of their servers is closest to the user who requested a file from it, and makes sure to load from that server. This also adds to the better loading speed significantly.
