Jq convert an object into an array - json

Question

I have the following file "Pokemon.json", it's a stripped down list of Pokémon, listing their Pokédex ID, name and an array of Object Types.
[{
"name": "onix",
"id": 95,
"types": [{
"slot": 2,
"type": {
"name": "ground"
}
},
{
"slot": 1,
"type": {
"name": "rock"
}
}
]
}, {
"name": "drowzee",
"id": 96,
"types": [{
"slot": 1,
"type": {
"name": "psychic"
}
}]
}]
The output I'm trying to achieve is, extracting the name value of the type object and inserting it into an array.
I can easily get an array of all the types with
jq -r '.pokemon[].types[].type.name' pokemon.json
But I'm missing the key part to transform the name field into it's own array
[ {
"name": "onix",
"id": 95,
"types": [ "rock", "ground" ]
}, {
"name": "drowzee",
"id": 96,
"types": [ "psychic" ]
} ]
Any help appreciated, thank you!

Answer 1

In the man it states you have an option to use map - which essentially means walking over each result and returning something (in our case, same data, constructed differently.)
This means that for each row you are creating new object, and put some values inside
Pay attention, you do need another iterator within, since we want one object per row.
(we simply need to map the values in different way it is constructed right now.)
So the solution might look like so:
jq -r '.pokemon[]|{name:.name, id:.id, types:.types|map(.type.name)}' pokemon.json
