分解数组，使第二个元素位于不同的数组中

function splitArray(arr) {
    if (arr.length < 2) {
        throw new Error("Array must have at least two elements");
    }

    // 创建一个新的数组，包含原数组的第二个元素
    const secondElementArray = [arr[1]];

    // 创建一个新的数组，包含除第二个元素外的所有元素
    const remainingElementsArray = arr.slice(0, 1).concat(arr.slice(2));

    return {
        secondElementArray,
        remainingElementsArray
    };
}

// 示例用法
const originalArray = [1, 2, 3, 4, 5];
const result = splitArray(originalArray);

console.log("Second Element Array:", result.secondElementArray); // 输出: [2]
console.log("Remaining Elements Array:", result.remainingElementsArray); // 输出: [1, 3, 4, 5]

if (arr.length < 2) {
    throw new Error("Array must have at least two elements");
}

const _ = require('lodash');

function splitLargeArray(arr) {
    const secondElement = _.nth(arr, 1);
    const remainingElements = _.drop(arr, 2);

    return {
        secondElementArray: [secondElement],
        remainingElementsArray: remainingElements
    };
}
