我如何将数组拆分成块，但让它逐个填充每个数组 [英] How can I split an array into chunks but have it fill each array by going one by one

问题描述

我正在使用此函数创建数组的块：

I'm using this function to create chunks of an array:

function chunkArray(myArray, chunk_size) {
    let results = [];
    while (myArray.length) {
        results.push(myArray.splice(0, chunk_size));
    }
    return results;
}

但是，如果我们假设原始数组是 [1,2,3,4,5,6] 我将它分成3个部分，我最终会得到这个：

However, if we assume that the original array is [1, 2, 3, 4, 5, 6] and I'm chunking it into 3 parts, I'll end up with this:

[
    [1, 2],
    [3, 4],
    [5, 6]
]

但是，我更愿意将它分成三个之间的数组，例如：

But, I'd instead like it to chunk into the arrays jumping between the three, ex:

[
    [1, 4],
    [2, 5],
    [3, 6]
]

最好的方法是什么？

推荐答案

您可以使用以下代码：

function chunkArray(myArray, chunk_size) {
    let results = new Array(chunk_size);
    for(let i = 0; i < chunk_size; i++) {
        results[i] = []
    }
    // append arrays rounding-robin into results arrays.
    myArray.forEach( (element, index) => { results[index % chunk_size].push(element) });
    return results;
}

const array = [1,2,3,4,5,6];
const result = chunkArray(array, 3)
console.log(result)
