What’s the simplest jq for mapping JSON array vals to dicts?

How can I make a key value dictionary using jq?

If I do: cat api_fm.json | jq -r "[ .[].name, .[].status ]"
I receive:

[
  "plugin",
  "c_docker_2",
  "c_docker_5",
  "c_docker_4",
  "c_docker_3",
  "c_docker_1",
  "Started",
  "Started",
  "Started",
  "Started",
  "Started",
  "Started"
]

So, I would like to map the name with the status like this:

[
   "plugin: started"
...
]

    Working through the requirements in your comment. Given:

    $ cat api_fm.json
[
  {"name":"plugin", "status":"Started"},
  {"name":"c_docker_2", "status":"Started"},
  {"name":"c_docker_5", "status":"Started"},
  {"name":"c_docker_4", "status":"Started"},
  {"name":"c_docker_3", "status":"Started"},
  {"name":"c_docker_1", "status":"Started"}
]

    We can produce tab-separated name-status pairs like

    $ jq -r '.[] | [.name, .status] | @tsv' api_fm.json
plugin  Started
c_docker_2  Started
c_docker_5  Started
c_docker_4  Started
c_docker_3  Started
c_docker_1  Started

    Then, to create the bash associative array

    declare -A prod

while IFS=$'t' read -r name status; do
    prod["$name"]=$status
done < <(
    jq -r '.[] | [.name, .status] | @tsv' api_fm.json
)

declare -p prod

    declare -A prod=([c_docker_2]="Started" [c_docker_3]="Started" [c_docker_1]="Started" [c_docker_4]="Started" [c_docker_5]="Started" [plugin]="Started" )
