How to get brew list as JSON output

Question

I am running brew list --versions to get this list:

    user@mac ~ [1]> brew list --versions
    fish 3.7.0
    ncurses 6.4
    pcre2 10.43
    syncthing 1.27.4
    appcleaner 3.6.8
    teamviewer 15.51.6

How can I put the output to a json object like this:

[
   {
      "name":"fish",
      "version":"3.7.0"
   },
   {
      "name":"ncurses",
      "version":"6.4"
   }
]

You can get directly json format with brew info:

brew info --json --installed | jq 'map({name, version:.installed[0].version})'
