Solution

#### Note:

This exercise has changed since this solution was written.

`Two-fer` or `2-fer` is short for two for one. One for you and one for me.

Given a name, return a string with the message:

``````One for X, one for me.
``````

Where X is the given name.

However, if the name is missing, return the string:

``````One for you, one for me.
``````

Here are some examples:

Name String to return
Alice One for Alice, one for me.
Bob One for Bob, one for me.
One for you, one for me.
Zaphod One for Zaphod, one for me.

## Setup

Go through the setup instructions for Javascript to install the necessary dependencies:

https://exercism.io/tracks/javascript/installation

## Requirements

Install assignment dependencies:

``````\$ npm install
``````

## Making the test suite pass

Execute the tests with:

``````\$ npm test
``````

In the test suites all tests but the first have been skipped.

Once you get a test passing, you can enable the next one by changing `xtest` to `test`.

## Submitting Incomplete Solutions

It's possible to submit an incomplete solution so you can see how others have completed the exercise.

### two-fer.spec.js

``````import { twoFer } from './two-fer'

describe('twoFer()', () => {
test('no name given', () => {
expect(twoFer()).toEqual("One for you, one for me.")
})

xtest('a name given', () => {
expect(twoFer("Alice")).toEqual("One for Alice, one for me.")
})

xtest('another name given', () => {
expect(twoFer("Bob")).toEqual("One for Bob, one for me.")
})
})``````
``````//
// This is only a SKELETON file for the 'Two fer' exercise. It's been provided as a
// convenience to get you started writing code faster.
//

export const twoFer = (name = 'you') => {
return `One for \${name}, one for me.`;
};``````
