将一个文本文件拆分为多个文本文件nodejs

const fs = require('fs');

fs.readFile('path/to/original.txt', 'utf8', (err, data) => {
  if (err) throw err;
  // 在这里进行拆分操作
});

const fs = require('fs');

fs.readFile('path/to/original.txt', 'utf8', (err, data) => {
  if (err) throw err;
  
  const lines = data.split('\n');
  // 在这里进行后续操作
});

const fs = require('fs');

fs.readFile('path/to/original.txt', 'utf8', (err, data) => {
  if (err) throw err;
  
  const lines = data.split('\n');
  
  lines.forEach((line, index) => {
    fs.writeFile(`path/to/split_${index}.txt`, line, 'utf8', (err) => {
      if (err) throw err;
      console.log(`Split file ${index} created.`);
    });
  });
});
