## Load Your Core JS Library through a CDN

### CDN - What and Why

CDN = Content Delivery Network

See: 3 reasons why you should let Google host jQuery for you (or any other CDN)

- Decreased latency
- Increased Parallelism
- Better Caching

### CDNs to Use

See: Using jQuery with a CDN

But not just jQuery! MaxCDN, Google, Microsoft, and cdnjs.com host several JS libraries through their CDNs:

- Google Hosted Libraries
- MaxCDN is used for several Open Source projects
- Microsoft Ajax Content Delivery Network
- cdnjs.com
- For a fuller list see: Free Open Source CDNs (That You'll Actually Use)
