Distinct Count with JsonAta of the resources in GCP project

 Scenario 

I need to get a quick picture of what resources a GCP project has and how many 

so according to this https://stackoverflow.com/a/60550886/60114 

I do 

gcloud asset search-all-resources --format=json --scope=projects/<GCP-PROJECT-ID>

I get a JSON that is an array of objects like 

```

{

    "additionalAttributes": {},

    "assetType": "compute.googleapis.com/Disk",

    "displayName": "terraform-demo-api",

    "location": "us-central1-c",

    "name": "//compute.googleapis.com/projects/prodeo-kn-demo/zones/us-central1-c/disks/terraform-demo-api",

    "project": "projects/857463209268"

  },

```

that I need to do distinct count by the assetType 

for this the JsonAta https://try.jsonata.org/  proved to be useful

this is the expression 

$merge(

$sort(

$merge(

$map(

$distinct($.assetType),

function($current)

{

{

$current : $count(

$filter(

$.assetType,

function($value, $index,$array){$value= $current}

)

)

}

}

)

)

)

)

output is like that 

{

"iam.googleapis.com/ServiceAccountKey": 8,

"compute.googleapis.com/Instance": 4,

"compute.googleapis.com/Disk": 4,

"compute.googleapis.com/Address": 1,

"compute.googleapis.com/Firewall": 6,

"compute.googleapis.com/InstanceTemplate": 4,

"compute.googleapis.com/Route": 25,

"compute.googleapis.com/Subnetwork": 24,

"compute.googleapis.com/Network": 1,

"cloudresourcemanager.googleapis.com/Project": 1,

"iam.googleapis.com/ServiceAccount": 4,

"appengine.googleapis.com/Application": 1

}
