I write JavaScript for a living, and I often forget if it's one word or two. It doesn't mean you don't know JS. And yes, we all know HTML isn't a programming language, but it's so essential to releasing software nowadays that it's almost a pointless distinction to separate it. One extra list item to point out that it's a markup language? That groaning sound you hear? It's every intro to programming deck having to laboriously expand by one slide for no good reason.
