Joining

Coercing eol.auto|eol.crlf|eol.lf|eol.cr to string yields the appropriate character. This is useful for joining.

String(eol.lf) // "\n"
eol.split(text).join(eol.auto) // same as eol.auto(text)
eol.split(text).filter(line => line).join(eol.auto) // text joined after removing empty lines
eol.split(text).slice(-3).join(eol.auto) // last 3 lines joined
