如何用JQ合并两个arrays的对应元素

Question

I have two arrays with the same amount of elements but with different keys/values. I want to integrate the key/value of the second array into the first for each index/position.

1.json

[    
    {
      "name": "xxx",
      "url": "yyy",
      "thumbnail": "nnn"
    },
    {
      "name": "bla bla",
      "url": "some-url",
      "thumbnail": "another-pic"
    }
]

2.json

[
    {
        "spotifyUrl": "first-spotify-url"
    },
    {
        "spotifyUrl": "second-spotify-url"
    }
]

The result I would like to achieve:

[    
    {
      "name": "xxx",
      "url": "yyy",
      "thumbnail": "nnn",
      "spotifyUrl": "first-spotify-url"
    },
    {
      "name": "bla bla",
      "url": "some-url",
      "thumbnail": "another-pic",
      "spotifyUrl": "second-spotify-url"
    }
]

I already tried different things but couldn't find the result I wanted. For example this one here:

jq -n '
  (input | map_values([.])) as $one
  | input as $two
  | reduce ($two|keys_unsorted[]) as $k2 ( $one;
      .[$k2] += [$two[$k2]] )
' 1.json 2.json

is almost what I want, except that the spotify-url is nested into its own object and looks like this:

[    
    {
      "name": "xxx",
      "url": "yyy",
      "thumbnail": "nnn"
    },
    {
      "spotifyUrl": "first-spotify-url"
    }
]

I appreciate any help and bet it's a lot simpler than I can think of. Thanks in advance.

It's easier than that.

jq -s 'transpose | map(add)' 1.json 2.json
