JSON Size Smaller Than MessagePack Go Implementation

[marcsantiago]

When pasting the JSON below into the official message pack site, it shows a significant decrease in size
https://msgpack.org/index.html

{"bar":"spam","foo":[{"spam":"ss","size":{"w":320,"h":480},"n":10,"c":1},{"spam":"ss","size":{"w":300,"h":250},"n":5,"c":1},{"spam":"ss","size":{"w":320,"h":50},"n":1,"c":1},{"spam":"v","size":{"w":-1,"h":-1},"n":20}],"l":10,"b":1}

However when using this package it always shows that the generated output is larger than it's JSON counter part. Any reason why?

Is the site applying compression as well?

I assume, there is the type saved in the []byte. When u store it as json, there is no type definition, its loose and will get duck typed while loading. I also assum this will make this implementation faster than a json encoding/decoding.

But thats just an assumption, i did not check the code, nor did i use it till now :D
