Suppose I have an array : ["1","2","3"]. How can I swap the first element 1 with the later one which is 2 ?
That is the end result to be ["2","1","3"]

As jq is tagged, how about the reverse function applied to the sublist containing the first two elements
jq '.[:2] |= reverse'
["2","1","3"]

More generically, if more prosaically:
def swap(i;j): .[i] as $t | .[i]=.[j]|.[j]=$t;
swap(0;1)
