What is the best technique for applying a filter to a JSON response?

In the JSON response I received, there are multiple attributes with various values. Before proceeding with any operation, I need to filter out the data based on the "is_sync_enabled" attribute being set to true. After filtering, I only want to read and retrieve the values of the "field_name" attribute from the modified JSON data.

If anyone has suggestions on how to achieve this filtering process effectively, it would be greatly appreciated. Thank you.

To achieve the desired result, you can utilize a combination of Array.filter along with Array.map.

When using Array.filter, specifically look for elements that have attributes present and where the attribute .is_sync_enabled is set to true.

Subsequently, employ Array.map to extract the field_name property from these selected attributes.

let data = { "links":{ "self":"https://xyz/v1/test/1/attributes" }, "data":[ { "type":"tenantFields", "id":1, "attributes":{ "field_name":"firstName", "is_required":false, "is_sync_enabled":true }, "relationships":{ }, "links":{ "self":"https://xyz/v1/test/1/attributes/1" } }, { "type":"tenantFields", "id":2, "attributes":{ "field_name":"lastName", "is_required":false, "is_sync_enabled":true }, "relationships":{ }, "links":{}, {"self":"https://xyz/v1/test/1/attributes/2"} }, { "type":"tenantFields", "id":3,"attributes":{ "field_name":"userTitle","is_required":false, "is_sync_enabled":false}, "relationships":{ }, "links":{"self":"https://xyz/v1/test/1/attributes/3"}}],"included":[]};
let results = data.data.filter(item => {
    return (item.attributes && item.attributes.is_sync_enabled);
}).map(item => { 
    return item.attributes.field_name;
});

console.log("Desired Output:", results);
