Yes! My entry point as well, back in the Macromedia days, making interactive animations with gotoAndStop. When AS3 appeared many years later weaned myself into the concepts of OOP, partly out of need, partly out of curiousity ... but mainly to understand other's work. Looking up to guys like mr doob. Frontend tooling today is insane. The flash ide and actionscript felt like a standard at the time, with a huge amount of power abstracted away. I feel like it's only in the past 5 years that the real standards have caught up with the (admiteddly inaccessible) possibilities of pre-2008.
