In jupyter-book/mystmd#30 we've now enforced a particular code style on the typescript (and implicitly, Javascript) codebase that we've got. In particular, I think this prettier configuration is what is used there:

jupyter-book/mystmd@c517f5c#diff-663ade211b3a1552162de21c4031fcd16be99407aae5ceecbb491a2efc43d5d2

So first of all, we should make sure that this is a 👍 for folks working on the Javascript side (maybe from the @executablebooks/web-team in particular). I don't know Javascript well enough to have strong opinions about code formatting there, though this seems reasonable enough to me.

If we agree that this is a good formatting choice, we should document it in our conventions so that others know what standard we should follow.
