如何使用JavaScript分隔数组以实现样式化目的

const array = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const chunkSize = 3;

const chunks = [];
for (let i = 0; i < array.length; i += chunkSize) {
    chunks.push(array.slice(i, i + chunkSize));
}

console.log(chunks); // 输出: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

const array = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const chunkSize = 3;

const chunks = array.reduce((chunks, item, index) => {
    const chunkIndex = Math.floor(index / chunkSize);
    if (!chunks[chunkIndex]) {
        chunks[chunkIndex] = [];
    }
    chunks[chunkIndex].push(item);
    return chunks;
}, []);

console.log(chunks); // 输出: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

const array = [1, 2, 3, 4, 5, 6, 7, 8];
const chunkSize = 3;

const chunks = array.reduce((chunks, item, index) => {
    const chunkIndex = Math.floor(index / chunkSize);
    if (!chunks[chunkIndex]) {
        chunks[chunkIndex] = [];
    }
    chunks[chunkIndex].push(item);
    return chunks;
}, []);

// 移除空数组
const filteredChunks = chunks.filter(chunk => chunk.length > 0);

console.log(filteredChunks); // 输出: [[1, 2, 3], [4, 5, 6], [7, 8]]
