There are four key features of Go's JSON handling package in coding JSON. Automatic type conversion, which automatically handles conversion between JSON and native Go types. Field visibility, which allow for the processing of only exported struct fields. Nested structures, that support complex data structures with nested objects and arrays. And error handling, which provides robust reporting for malformed JSON or type mismatches. All of these features make things useful, especially in API development. Let's look at an example.
