Intermediate Algorithm Scripting - DNA Pairing

JavaScript
1

Tell us what’s happening:
I am trying to solve the algorithm test on DNA pairing. It only returns for the first element only. Kindly help to understand where I am messing. I will greatly appreciate.

Your code so far

function pairElement(str) {
  let arr = [];
  let splitStr = str.split('');
  console.log(splitStr);
  for(let i = 0; i < splitStr.length; i++){
    if(splitStr[i] === 'G'){
    arr.push(['G', 'C']);
  } else if(splitStr[i] === 'C'){
    arr.push(['C', 'G']);
  }else if(splitStr[i] === 'A'){
    arr.push(['A', 'T']);
  } else if(splitStr[i] === 'T'){
    arr.push(['T', 'A']);
  }
  return arr;
  }
}

console.log(pairElement("GCG"));
