Iterator file lines (naive version)

lines.js

import fs from 'fs/promises';

async function* lines(path) {
  const content = await fs.readFile(path, { encoding: 'utf-8' })
  const lines = content.split(/\n/)
  for (const line of lines) {
    yield line
  }
}



for await (let i of lines('app.mjs')) {
  console.log('>>' + i)
}
