这个示例中,目标数组targetArray是一个二维数组,给定数组givenArray只包含一个元素2。通过调用filterArray函数,并传入这两个数组作为参数,就可以得到符合条件的结果数组filteredArray,即包含给定数组元素2的子数组。 优势: 该算法具有以下优势: 灵活性:可以适用于任意大小和维度的目标数组和给定数组。
let argState = Array.isArray(args[0]) ? args[0] : args; // Filter out elements from the array that are not included in the `args`. let pulled = arr.filter((v, i) => !argState.includes(v)); // Clear the original array and push the filtered elements back into it. arr....
