如何使用typescript删除数组重复？

const arr = [1, 2, 3, 3, 4, 5, 5];
const uniqueArr = Array.from(new Set(arr));
console.log(uniqueArr); // [1, 2, 3, 4, 5]

const arr = [1, 2, 3, 3, 4, 5, 5];
const uniqueArr = arr.filter((value, index, self) => {
  return self.indexOf(value) === index;
});
console.log(uniqueArr); // [1, 2, 3, 4, 5]

const arr = [1, 2, 3, 3, 4, 5, 5];
const uniqueArr = arr.reduce((prev, curr) => {
  if (!prev.includes(curr)) {
    prev.push(curr);
  }
  return prev;
}, []);
console.log(uniqueArr); // [1, 2, 3, 4, 5]
