Bunch.io Code Challenge

First of all I wanted to showcase an end2end delivery rather than focus on the specifics.

This challenge makes use of the following stack:

TODOS

fix propertyTypes required errors in console
add testing to assert core logic done at reducers
deeper componetize StepsComponent
Better handle UX interactions, e.g. form submit on enter, etc.
Add auth for users
use localstorage for saving steps
use BE for any transaction: e.g steps data should be pushed on every step and not at the end of the questionare
use BE to retrieve next step data and leverage database performance on lookup

Didn't have time to accomplish with the TODOS, in general I was very motivated by the code challenge. Please find additional comments along the code.

Additional metadata could be used to greater improve the core logic used to propose questions:

ATM only these fields are taken into account when proposing the next set of questions:

dimensions.used dimensions.selected

answers.selected answers.unselected

It will be interesting to provide a slider to let users rate the difficulty of the two questions being exposed, this way this additinal metadata could be used to retrieve answers based on difficulty
We could track the amount of time a user takes to answer the question as an additional dificulty metadata, and take into consideration this information for analitics and to dynamically filter answers for next steps
