Tell us what’s happening:
Hi there, I believe this solution is correct. I checked that on the console and it works fine. It does not seem to satisfy fCC though.
Any advice?
Thanks,

Your code so far
function pairElement(str) {
const pairsObj = {
A: "T",
T: "A",
C: "G",
G: "C"
}
let res = [];
for(let i = 0; i < str.length; i++) {
res.push( [ [ str[i], pairsObj[str[i]] ] ] );
}
return res;
}
pairElement("ATCGA");
