6 years ago Another issue: we should have better error output/tolerance when there's a typo for "big brother name." This case can also happen if we inconsistently use nicknames (e.g., "Alexander" vs. "Alex").
Right now, this is fatal and with a cryptic error message ("Cannot read property 'id' of undefined"). We should consider clearer error output, and explicitly decide whether or not this should be a fatal error.
Data might be in an unexpected format (e.g., someone might lack both a "big bro" and a "family started" due to data entry mistakes). This is something we can easily handle in the code.
We could either add these guys to a separate family (named "UNKNOWN") or output warnings/errors in the console.
