(JS-0116) async function should have await expression

[whitlocktech]

Description

A function that does not contain any await expressions should not be async (except for some edge cases in TypeScript which are discussed below). Asynchronous functions in JavaScript behave differently than other functions in two important ways:

Occurrences

const server = http.createServer(app)

async function startServer() {
  server.listen(PORT, () => {
    mongoConnect()
    console.log(`Server is running on port ${PORT}`)
  })
}

startServer()

  console.error('Mongoose Connection Error', err)
})

async function mongoConnect() {
  mongoose.connect(MONGO_URL)
}

async function mongoDisconnect() { 
  await mongoose.disconnect()
