It’s one of the topics I feel I’m too biased since I spend 10 years as a flash developer. The requests for widgets and or small applications we got where simply impossible to write in a frontend only fashion at the time. And a lot of my peers moved on to work on HTML5 which was pushed hard as the successor at the time. A lot felt like a step back. I moved to native iOS and worked on games in cocoa 2D. I remember that I thought more than once: “This was already solved in flash”. But I think in the end it’s a good thing that we don’t have or need the flash player anymore. I wish only we could have gotten a flash to wasm/webgl compiler or flash to js transpiler. ActionScript 3 was great and leagues ahead of JavaScript at the time.
