Adobe Animate - does it worth?

[AS3.0]

Really when you are converting as3 to js/html5 that's for your old projects that you want to port to something native, but if you plan on typing current as3 projects and than porting it to html5 that's not going to be the most light weight as typing the js/html5 yourself on a text editor, because all the libraries they include that maybe your site wont really need, typing html5/js is generally free and if you can use a text editor you should but the main focus is really the faster languages like as3, you should compile as3 to swf/apk/ipa/exe like on my channel you can see that it is possible to extend the language to add Bluetooth/chromeless/notification bar messages or for any new os updates you can learn to write the extension plugins yourself to activate new os features that get released so as3 is never really deprecated and when its very old you can still activate new features if you implement them.
