基于设置的间隔合并数组(javascript)

function mergeArrays(arrays, interval) {
    let result = [];
    let index = 0;
    let maxLen = arrays.map(arr => arr.length).reduce((a, b) => Math.max(a, b), 0);

    for (let i = 0; i < maxLen; i += interval) {
        for (let arr of arrays) {
            if (i < arr.length) {
                result.push(arr[i]);
            }
        }
    }

    return result;
}

// 示例数组
let array1 = [1, 2, 3, 4];
let array2 = ['a', 'b', 'c', 'd'];
let array3 = [true, false, true, false];

// 合并数组，间隔为2
let mergedArray = mergeArrays([array1, array2, array3], 2);
console.log(mergedArray); // 输出: [1, 'a', true, 3, 'c', false]
