JSON to Go struct

Questions

Why are nested objects anonymous structs?+

Because naming them would mean inventing names the sample never gave you. An anonymous struct is valid Go and pastes straight in; lift a nested one into a named type when you need to pass it around.

When do I get a pointer?+

When the sample showed null for that field. A pointer is the only way Go can tell an absent value from a zero one, which is why a nullable string comes out as *string rather than string.

Why int64 rather than int?+

Because JSON numbers are 64-bit floats and an id that fits today may not fit on a 32-bit build. Narrow it by hand where you know the range.
