I miss jQuery. It's funny that an argument against jQuery is "oh, but you have to load that big thing to access your site", but then we'll create Single Page Apps that then proceed to spend loading json for 10 seconds before we start interacting with them. :)

The techniques listed in that website aren't really used for single-page apps.

They're listing APIs that you used to need jQuery for that are now natively supported by the browser. This is for people still doing the jQuery style of development.
