node.js find attributes with same value in multiple JSON files

Question

Hey I would like to ask if it is possible to find lets say in 10 JSON files which are looking like this:

1.json:

{
  "name": "Miami",
  "attributes": [
    {
      "att_type": "People",
      "value": "1000"
    },
    {
      "att_type": "Cars",
      "value": 300
    }
  ]
}

2.json:

{
  "name": "New York",
  "attributes": [
    {
      "att_type": "People",
      "value": "5000"
    },
    {
      "att_type": "Cars",
      "value": 900
    }
  ]
}

And so on... just different attribute values. Lets say I want to find only towns with People > 2500 and I'm not even sure if it is possible or do I need to upload the json files to some database perhaps?

Thank you.

 const data = [{ "name": "Miami", "attributes": [{ "att_type": "People", "value": "1000" }, { "att_type": "Cars", "value": 300 } ] }, { "name": "New York", "attributes": [{ "att_type": "People", "value": "5000" }, { "att_type": "Cars", "value": 900 } ] } ] const result = data // find cities with attribute `People` with value greater than 2500.filter(d => +d.attributes.find(attr => attr.att_type === 'People').value > 2500) // get name of the city.map(d => d.name) console.log(result)
