Some packages need maybe an update :)

core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

Warning get when I do a npm install canvas-sketch-cli@latest -g

Thanks for the tip. I think a lot of the babel/es6 stuff here may be obsolete at this point—browsers have come a long way and most of these features work across the board now. I have been mostly pulling my hair out with babel the last few years, so would be a nice change to get away from it. I think this could be an option for future version of the library to simplify it and make it more future-facing.
