Is the code below valid?

var cb0 = function (req, res, next) {
  console.log('CB0')
  next()
}
var cb1 = function (req, res, next) {
  console.log('CB1')
  next()
}
app.get('/example/d', [cb0, cb1], function (req, res, next) {
  console.log('the response will be sent by the next function ...')
  next()
}, function (req, res) {
  res.send('Hello from D!')
})
