Fix Random Minor Issues in `slice2js` and `NOLINT`s

[InsertCreativityHere]

While planning out how to add @remarks to (Java/Type)Script, I came across a few inconsistencies, that I'd rather fix in a PR separate to the @remarks one.

There were also 2 formatting mistakes in our NOLINTs that I've been aware of a little while. Figured I might as well fix them now too.
