# 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.
