added an alternate version
Aug 1, 2019 at 15:22 comment added Pablo Lozano Another option with replace and 26 characters: s=>s.replace(/./gs,'$&$&')
Jul 31, 2019 at 12:30 comment added Oliver @KevinCruijssen Yeah, I agree :-)
Jul 31, 2019 at 12:29 comment added Kevin Cruijssen @Oliver I don't think it's valid. My 05AB1E would have a few 1 byte solutions in that case. Default I/O for a string is either, well.. a string, or a list/array/stream of characters / single-char strings. ["aa","bb","cc"] is a list of strings however, neither a string nor list of characters of itself. Adding a join or flatten it to a list of characters is valid, but would have to be counted towards the byte-count.
Jul 31, 2019 at 12:25 comment added Oliver @KevinCruijssen The join('') should take care of that. On second thought, that may be augmenting the output in a non-standard way so that may not be valid.
Jul 31, 2019 at 12:22 comment added Kevin Cruijssen @Oliver Won't that result in something like ['a','b','c'] -> ['aa','bb','cc'] instead of the intended ['a','a','b','b','c','c'], though?
Jul 31, 2019 at 12:19 comment added Oliver Would s=>s.map(c=>c+c) not work?
Jul 31, 2019 at 10:47 comment added Arnauld @NahuelFouilleul Good catch. Thanks!

fixed the 2nd version
Jul 31, 2019 at 10:43 comment added Nahuel Fouilleul s=>s.replace(/./gs,c=>c+c) so that . also matches newlines
