如何从数组中删除所有具有相同值的结构

function removeDuplicates(arr) {
  const countMap = {};
  const result = [];

  // 记录每个值出现的次数
  for (let i = 0; i < arr.length; i++) {
    const value = arr[i];
    countMap[value] = (countMap[value] || 0) + 1;
  }

  // 将不重复的值添加到新数组中
  for (let i = 0; i < arr.length; i++) {
    const value = arr[i];
    if (countMap[value] === 1) {
      result.push(value);
    }
  }

  return result;
}

const arr = [1, 2, 3, 2, 4, 3, 5];
const result = removeDuplicates(arr);
console.log(result); // 输出 [1, 4, 5]
