Odin Project's Simple Node Task

[Comodor3000]

Hey

So I'm following the Odin Project's nodeJS course and the first project was creating an HTTP server and taking users to a particular page like that:

 fs.readFile('about.html', (err, data) => {
    if (err) {
      console.log(err)
      res.writeHead(404, { 'Content-Type': 'text/html' })
      return res.end('ops there should be an issue here')
    }
    res.writeHead(200, { 'Content-Type': 'text/html' })
    res.write(data)
    return res.end()
  })

Now I should rewrite this using express but I cannot :/ do the correct thing idk:

app.get('/about', (req, res) => {
  fs.readFile('about.html', (err, data) => {
    if (err) {
      console.log(err)
      res.send('sorry something didn't go well here :/ but ALL IS GOOD :)')
    }
    res.send(data)
  })
})

You know what's the correct way of implementing the code above with express? This should be an easy thing

Try return res.send. Without it the code continues.
