JavaScript has both vertical tab \v and form feed \f as escape sequences
JSON includes form feed \f but not vertical tab
why?
@whitequark This is utterly stupid (no reason to break precedent) but probably FF was deemed somewhat useful (appears in lots of document formats, even source code files) and VT rather useless (I don't think I've ever seen it in practice).
@dalias nobody outside of GNU ever used \f
@whitequark @dalias I have never seen either outside of an ascii table.
@azonenberg @whitequark @dalias My brother is more of a NetBSD guy than GNU, and he uses form feed. It is elisp source though, so definitely some GNU influence: https://paredit.org/releases/26/paredit.el
