Naive Bubble Sort

var bubbleSort = function(array){
  for(var i = 0; i < array.length-1 ; i++){
    for(var j = 0; j < array.length-1 ; j++ ){
      if(array[j]>array[j+1]){
        var swap = array[j];
        array[j] = array[j+1];
        array[j+1] = swap;
      }
    }
  }
};

var sorted = bubbleSort([5,4,3,2,1]);
