js 集合[1,2,2,3,3,5],写一段脚本将重复的元素找出来
可以使用以下脚本来找出重复的元素： ```javascript function findDuplicates(arr) { var duplicates = []; var counts = {}; for (var i = 0; i < arr.length; i++) { var num = arr[i]; counts[num] = counts[num] ? counts[num] + 1 : 1; } for (var key in counts) { if (counts[key] > 1) { duplicates.push(Number(key)); } } return duplicates; } var arr = [1, 2, 2, 3, 3, 5]; var duplicates = findDuplicates(arr); console.log(duplicates); ``` 这段脚本会将重复的元素保存在一个新的数组中，并打印出结果。在这个例子中，输出结果应为 [2, 3]。 [2024-04-01 18:01:38 | AI写代码神器 | 502点数解答]
