# Solution

|
## Time spent
|
|
|
|
|
|
|
|
|
|
By major chunks of work in git history:
|
|
|
|
|
|
|
|
|
|
* ~0.5 hours to set up the project;
|
|
|
|
|
* ~5 hours to implement game board serialization, tic-tac-toe rules and game solver (with tests);
|
|
|
|
|
* ~1 hour to set up the backend / frontend structure with JSX templating and static resources;
|
|
|
|
|
* ~2 hours to implement progressively enhanced form and query string value trackers
|
|
|
|
|
(both on backend and in web components);
|
|
|
|
|
* ~3 hours to implement basic game UI in client-server mode;
|
|
|
|
|
* ~2 hours to enhance the most basic game UI features on frontend for offline mode;
|
|
|
|
|
* ~2 hours to make UI fully functional,
|
|
|
|
|
to cleanup the code and reduce duplication between frontend and backend,
|
|
|
|
|
and to make the resulting page somewhat presentable
|
|
|
|
|
* ~2 hours to implement another set of tic-tac-toe rules (with tests),
|
|
|
|
|
support for changing board size (both on backend and in web components).
|
|
|
|
|
|
|
|
|
|
...which makes it ~18 hours total. I definitely did not expect to spend that much;
|
|
|
|
|
but also originally I didn't think that the scope will expand this much.
