Writing JavaScript and making sure my web UI gets laid out exactly as I intend makes me feel like I'm making a UI in a word processor that has a very advanced macro system — but it's still a word processor at its core. Flash on the other hand felt more like a proper programming environment. A shame it was proprietary. And a big shame Adobe didn't open-source Flash Player after discontinuing it.
