I was surprised by this one that only showed up lower in the document:

- Date: only Date.now() is supported. [0]

I certainly understand not shipping the js date library especially in an embedded environment both for code-size, and practicality reasons (it's not a great date library), but that would be an issue in many projects (even if you don't use it, libraries yo use almost certainly do.

Good catch. I didn't realize that there was a longer list of restrictions below the section called "Stricter mode", and it seems like a lot of String functions I use are missing too.
