Static doesn’t mean no JavaScript or interaction. In fact many SPAs are just static pages served out of S3 and connecting directly to some API server to fetch data.

A static page means no processing is done on a web server to serve you the rendered content. This saves you time and money, and ensures scalability for any amount of traffic.

There are different meanings. Back in the day there was DHTML, where D stands for dynamic. So static page 10 years ago would mean no javascript.
