Как отсортировать одномерный массив точек, с учётом расстояния между ними?

var sourceList = [11, 14, 15, 17, 27, 28, 32, 52, 53, 54, 55, 56, 57, 75, 90, 97];
   sourceList.sort();

   var max_d = 9, K = 4;
   
   var result = [];
   var sequence = [sourceList[0] - max_d];

   sourceList.forEach(num => {
      if(num - sequence[sequence.length - 1] >= max_d) {
         if(sequence.length >= K) result = sequence;
         sequence = [];
      }
      sequence.push(num);
   });
   if(sequence.length >= K) result = sequence;

   console.log(result);
