Thanks so much for working on this! Going to loop @Qianqianye here as well :)

No problem! I made the changes live on Twitch so it provided educational value too 😄

Thanks @lindapaiste for consolidating all the files so only defaultHTML in createDefaultFiles.js needs to be updated!

Thanks @SableRaf and @raclim. I just double checked the version at web editor page, and it seems like that the version is not updated yet.

I haven't deployed these updates to production yet, since I'm still testing the mirror I replaced the missing console-feed package with. I'll keep you all posted when it's live, which should definitely be sometime this week!

@Qianqianye Just deployed the editor, which should reflect the new p5.js version!! I'll probably update the p5.js version for the Examples too by next week!
