Corrected formatting, for leaderboard
  • # jq, 16 bytes, preferably `-rR`
  • `./""|reverse|add`
  • Annoyingly, jq has convenient things like implicit I/O, and annoying
  • things like *adding* strings, but you can't `reverse` a string >:|.
  • `./""`&`add` are slightly shorter than the more obvious
  • `split("")`&`join("")`. The division operator splits a string, and `add` adds
  • all the elements of an array together, using string concatenation in this
  • case.
  • # jq, 16 bytes, preferably `-rR`
  • ```js
  • ./""|reverse|add
  • ```

a shorter way to split

  • `explode|reverse|implode`

`explode|reverse|implode`

Annoyingly, jq has convenient things like implicit I/O, and annoying
things like *adding* strings, but you can't `reverse` a string >:|.

`explode`&`implode` are slightly shorter than the more obvious `split("")`&`join("")`.
