Those 2 keywords are JS features, and p5.js, which is a frontend library, can’t change that:

As I have already mentioned to you on your previous forum thread:

B/c they don’t even acknowledge ECMA Script Modules (ESM / “.mjs”) exist anywhere on their docs, it’s no wonder their “p5.js Web Editor” doesn’t seem to be compatible w/ ESM either!

Pretty much any other JS code hosting/editor solution available should work!

For example, you can try out:

- [OpenProcessing.org](http://OpenProcessing.org)
- [Glitch.com](http://Glitch.com)
- [GitHub.com](http://GitHub.com)

And many others to host JS code + p5.js library!
