With Python:

from collection import Counter
Counter(s).most_common(1)[0][0]

With javascript 

function mostCommonCharacter(s) {
  var counter = {}
  var max = 0;
  var mostCommon;

  for (var x of s)
    counter[x] = (counter[x] || 0) + 1;

  for (var chr in counter)
    if (counter[chr] >= max) {
      max = counter[chr];
      mostCommon = chr;
    }

  return mostCommon;
}
