the article says it is possible to build web applications that use htmx for a smoother experience if javascript is enabled, but that properly falls back to vanilla HTML if js is not enabled

this is called progressive enhancement[1], and yes, htmx can be used in this manner although it requires some effort by the developer

unpoly, another hypermedia-oriented front end library, is more seamless in this regard and worth looking at
