Is it better to host Javascript in my theme or use a CDN?

Should I host my own Javascript {{ "javascript.js" | asset_url }} in my theme or is it better to use the javascript library cdn?

I would load as many assets as you can in your own theme, that will cut down on the number of different 3rd party resources needed, this way your code loads directly from your site's server (Shopify CDNs).

If you want to dive into optimizing 3rd party scripts this is a good article: https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/loading-thi...
