Optional and for the fun of showing off

This exercise connects client side fetch() (A03) with the server side JSON REST API (grade 4 above).

1. Add a page lotto.html that has client side JavaScript where the user can enter a serie of figures through a HTML form element, when a submit button is pressed the row is sent to the server, through lotto-json. The JSON response is retreieved in the page, and without reloading the page it is updated showing how many hits you had with your lotto serie.
