An application (like maps) and an online brochure are two different animals. A brochure for a company with a hundred or fewer products should generally be able to do fine with just HTML. Maybe a generator engine can assist with formatting, but there should be little need to add JavaScript unless you really really think eye-candy is important to sales. For a child or teen, maybe such gimmicks matter, but not for a furniture store. If you really need a fancy store with shopping carts and wish lists etc., there are plenty of online services you can rent for small and medium stores.
