从数组中删除绑定了不同参数的同一函数

function removeDuplicateFunctions(arr) {
  for (let i = 0; i < arr.length; i++) {
    for (let j = i + 1; j < arr.length; j++) {
      if (arr[i].toString() === arr[j].toString()) {
        arr.splice(j, 1);
        j--;
      }
    }
  }
  return arr;
}

// 示例用法
const arr = [
  function(a) {
    console.log(a);
  },
  function(b) {
    console.log(b);
  },
  function(a) {
    console.log(a);
  }
];

const result = removeDuplicateFunctions(arr);
console.log(result);
