JQ : Output with static value / variable

I want to have an output with static value using jq with static value :4546

nodes.json

{
  "nodes": {
    "node1.local": {
      ":ip": "10.0.0.1",
      "ports": [],
      ":memory": 1024,
      ":bootstrap": "bootstrap.sh"
    },
    "node2.local": {
      ":ip": "10.0.0.2",
      "ports": [],
      ":memory": 1024,
      ":bootstrap": "bootstrap.sh"
    },
    "node3.local": {
      ":ip": "10.0.0.3",
      "ports": [],
      ":memory": 1024,
      ":bootstrap": "bootstrap.sh"
    }
  }
}

here is my command use

ips=`jq -c '.nodes | to_entries | map(.value.":ip")' nodes.json`
echo $ips

where the output is 

["10.0.0.1", "10.0.0.2", "10.0.0.3"]

and i want it to be like this

["10.0.0.1:4546", "10.0.0.2:4546", "10.0.0.3:4546"]

Another try :

jq '[.nodes[][":ip"]+":4546"]' nodes.json

You could use map_values 

 jq -c '.nodes | to_entries | map(.value.":ip")| map_values(.+":4546")' nodes.jso

You can simply use + operator:

jq '.nodes | to_entries | map(.value.":ip" + ":4546")'
