从批处理文件的逗号分隔列表中删除重复项

function removeDuplicatesFromList(list) {
  // Step 1: Convert comma-separated list to array
  var array = list.split(',');

  // Step 2: Remove duplicates
  var uniqueArray = [];
  var set = new Set();
  for (var i = 0; i < array.length; i++) {
    if (!set.has(array[i])) {
      uniqueArray.push(array[i]);
      set.add(array[i]);
    }
  }

  // Step 3: Rebuild comma-separated list
  var newList = uniqueArray.join(',');

  return newList;
}

// Example usage
var inputList = "apple,banana,orange,apple,grape,banana";
var outputList = removeDuplicatesFromList(inputList);
console.log(outputList);
