Multiplying two objects will merge them recursively: this works like addition but if both objects contain a value for the same key, and the values are objects, the two are merged with the same strategy.
Unfortunately, it doesn't merge/concatenate arrays. Sometimes that's what you want (you want the 2nd value to override the 1st but sometimes not.
If you want it to concatenate instead, here are some workarounds:

If you only need/want to concatenate for some fixed list of keys, you could do it more simply like this (but could get repetitive to repeat for each key you want it for):
⟫ jq -n '[{hosts: ["a"]}, {hosts: ["b"]}] | .[]' | jq -s '.[0] * .[1] * {hosts: (.[0].hosts + .[1].hosts)}' { "hosts": [ "a", "b" ] } -

jq uses the Oniguruma regular expression library, as do php, ruby, TextMate, Sublime Text, etc, so the description here will focus on jq specifics.
