Idiom #120 Read integer from stdin

Read an integer value from the standard input into variable n.

Code 
const {createInterface} = require('readline')

const rl = createInterface ({
  input: process.stdin,
  output: process.stdout
})

rl.question('Input an integer: ', response => {
  let n = parseInt (response)
  // stuff to be done with n goes here

  rl.close()
})

This example only works with nodeJS (server-side JS) because browser JS does not have a standard input.
