JS使数组中的所有值都不同

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

const array = [1, 2, 2, 3, 4, 4, 5];
const uniqueArray = array.filter((value, index) => array.indexOf(value) === index);
console.log(uniqueArray); // 输出 [1, 2, 3, 4, 5]

const array = [1, 2, 2, 3, 4, 4, 5];
const uniqueArray = array.reduce((accumulator, value) => {
  if (!accumulator.includes(value)) {
    accumulator.push(value);
  }
  return accumulator;
}, []);
console.log(uniqueArray); // 输出 [1, 2, 3, 4, 5]
