Pointless JavaScript is a bad thing. Want to take over the scrolling just because you dislike the default one? Please don't. Also, I believe that by this point the novelty of scroll animations (used to be popular a couple of years ago) has worn off. Want to include a billion JS tracking services on your mostly-textual webpage? Please, make sure they don't interfere with the rest of the page. Want to include cool charts, even if they're not interactive? Tables with sortable, re-arrangeable columns? Forms with smart autocomplete that narrows choices based on previous choices? Shopping cart? Chat? Anything that will re-render the entire page for changes on less than 1/2 of the page? Yes, please use JavaScript.
