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)
