如何拆分CSV行，然后复制该行？

import csv

# 读取CSV文件
with open('example.csv', newline='') as csvfile:
    reader = csv.reader(csvfile)
    
    # 遍历每一行
    for row in reader:
        # 拆分行并打印
        print(row)
        
        # 复制该行
        copied_row = row.copy()
        print("Copied Row:", copied_row)

const fs = require('fs');

// 读取CSV文件
fs.readFile('example.csv', 'utf8', (err, data) => {
    if (err) throw err;
    
    // 按行分割数据
    const lines = data.split('\n');
    
    lines.forEach(line => {
        // 拆分行并打印
        const fields = line.split(',');
        console.log(fields);
        
        // 复制该行
        const copiedFields = fields.slice();
        console.log("Copied Row:", copiedFields);
    });
});
