// Function to find duplicates in an array function find_duplicate_in_array(arra1) { // Object to store the count of each element in the array var object = {}; // Array to store the elements with duplicates var result = []; // Iterate through each element in the array arra1.forE...
上述代码定义了一个findDuplicates函数,它接受一个数组作为参数,并返回该数组中的重复值。该函数使用一个对象uniqueValues来记录数组中的唯一值,并使用一个数组duplicates来存储重复值。通过遍历数组,如果当前值已经存在于uniqueValues对象中,则将其添加到duplicates数组中。 这只是一种实现方式,还有其他方法可以找到数组中...
2) Remove duplicates using filter and indexOf TheindexOf()method returns the first index at which a given element can be found in the array, or -1 if it is not present. Thefilter()method creates a shallow copy of a portion of a given array, filtered down to just the elements from t...
