to Two Fer in the JavaScript Track

Test suite


This solution was written on an old version of Exercism. The tests below might not correspond to the solution code, and the exercise may have changed since this code was written.

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

"One for X, one for me."

When X is a name or "you".

If the given name is "Alice", the result should be "One for Alice, one for me." If no name is given, the result should be "One for you, one for me."


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



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.

import twoFer from './two-fer';

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

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

  xtest('another name given', () => {
    const name = 'Bob';
    expect(twoFer(name)).toEqual('One for Bob, one for me.');
module.exports =
class {
  twoFer(who = 'you') {
    return `One for ${who}, one for me.`
