How to print sub-items of a key?

[BlueFalconHD]

I have a file, assets.json:

{
 "window":{
         "bottom":"_"
 }
}

I tried to cat the file while piping it with JSON:
cat assets.json | json window bottom
which outputs:

{
  "bottom": "_"
}

I want it to just output the value of the key bottom.

Like:

cat assets.json | json window.bottom

Of course! I was looking through the issues searching for an answer to an issue I'm coming across with arrays. Figured might as well help anyone who runs into the issue.
