Objx provides the objx.Map type, which is a map[string]interface{} that exposes a powerful Get method (among others) that allows you to easily and quickly get access to data within the map, without having to worry too much about type assertions, missing data, default values etc.

Objx uses a predictable pattern to make access data from within map[string]interface{} easy. Call one of the objx. functions to create your objx.Map to get going:

m, err := objx.FromJSON(json)
