Probably titled this one badly, will try and explain a bit better.
Basically I've been trying to make a function:
var readlineSync = require('readline-sync');
function i(context) {
readlineSync.question(context)
}
var Username = i("Testing the prompt: ")
console.log(Username)
I find having to write readlineSync.question over and over again rather irritating, but running the code returns this:
Testing the prompt: Hello
undefined
Am I doing something wrong?
You're not returning anything from the function.
It should be:
function i(context) {
return readlineSync.question(context)
}
You could just do:
var i = readlineSync.question
// usage
i('Testing the prompt: ')
Creating an alias of the function
Or, if you are using an ES6 capable environment (Node 6 or Chrome):
import { question as i } from 'readline-sync'
// usage
i('Testing the prompt: ')
Which is the same of:
var i = require('readline-sync').question
// usage
i('Testing the prompt: ')
you forgot the return statement
function i(context){
return readlineSync.question(context)
}
