getting started

1. fork git repository
2. git clone your fork
3. install npm packages npm install
4. testing:
   • unit (jest): npm run test
   • lint (eslint): npm run lint
5. create merge/pull request from your fork

• NB: make each task as a separate commit!
• Check examples.js for code usage examples

• lint: fix all linting errors (do not make new errors in future)
• unit: use snapshot testing to test src/user.js (use ids 1, 56 and 1345)
• unit: use string as input(id) for src/user.js - test that exception is given
• unit: write implementation (capitalize.js) for this test (you can use npm packages in capitalize.js)

// src/capitalize.spec.js
const capitalize = require('./capitalize');

describe('sum', () => {
  it('triin => Triin', () => {
    expect(capitalize('triin')).toBe("Triin");
  });
  it('error - bad input', () => {
    expect(() => {
      capitalize({ "word": 'cat' });
    }).toThrow(/bad input/);
  });
});

• unit: test src/randomPlus.js while mocking src/random.js (check from mock that random params was 1 and 99)
