marshmallow
Marshmallow provides a flexible and performant JSON unmarshalling in Go. It specializes in dealing with unstructured struct - when some fields are known and some aren't, with zero performance overhead nor extra coding needed. (by PerimeterX)

Why Go is the Future of Backend Development
Also, JSON marshaling and unmarshaling may also be an issue. C/C++ are quite varied - I suppose they either use the fields of the JSON as is, or use some ugly-ass macros (u/xkcd-Hyphen-bot, do your thing. It actually fits here), but Go entries would probably used the standard way to do this in Go - the encoding/json package - which needs to read and parse struct field tags at runtime. Does it at least cache the parsed definitions? From the complaints I see about it, I doubt it. Also, there seems to be Marshmallow that can do caching (among other optimizations) and greatly outperforms the build in one. I guess that means the standard library implementation doesn't do it? That would explain why the TechEmpower benchmark entries are so slow - I don't think they use Marshmallow. Marshmallow has less than 300 starts on GitHub, which is far less than what you would expect it to have if it was commonly used.

JSON array with two different json objects
I believe this was one of the reasons for marshmallow being written: https://github.com/PerimeterX/marshmallow The idea to partially unmarshal, inspect the type field, and then make a second pass.

Marshmallow - a JSON unmarshalling library for flexible use cases like some known and some unknown fields, or prevention of data loss
Marshmallow is used internally at PerimeterX for some time, and we've recently decided to open-source it and share a blog post about how it helped us trim 70% of our JSON parsing costs in production.

Introducing astjson: Transform and Merge JSON Objects with Unmatched Speed in Go
In this article, I will introduce you to a new package called astjson that I have been working on for the last couple of weeks. It is a Go package that allows you to transform and merge JSON objects with unmatched speed. It is based on the jsonparser package by buger aka Leonid Bugaev and extends it with the ability to transform and merge JSON objects at unparalleled performance.

What's the best way to unmarshall this nested JSON?
Use this to extract the data value, and handle/unmarshal it accordingly.

Why the heck am I getting an empty byte array trying to read a simple json file?
I was actually just trying to get it into a []byte to use this package which claims it works well for unknown data structures.

Whats the fastest JSON unmarshaling package as of right now?
If you don't know the schema or you only need to access one or two fields in a much larger JSON object, I would recommend https://github.com/buger/jsonparser as it provides an easy API to access specific values without fully unmarshaling. This is an unusual use case though, 9 times out of 10 I would tend to use easyjson.
