There are two ways to get the last item from an array using
jq
.
The one that is perhaps a bit more intuitive is to pipe the array to the
last
function.
$ echo '[1,2,3]' | jq '. | last'

Another approach is to use an array index
expression to positionally
grab the last element of the array. As is the case with some languages and
libraries, -1
positionally refers to the last item in the array.
$ echo '[1,2,3]' | jq '.[-1]'
