Navigating a intricate JSON structure using JavaScript - the ultimate guide!

I am facing a challenge with a complex JSON object that I need to traverse and add additional properties to. Below is an example of the JSON structure:

Object {root: Object}
      root: Object
          entity_children: Array[1]
              0: Object
                  entity_children: Array[1]
                     0: Object
                         entity_children: Array[10]
                            0: Object
                            1: Object
                            2: Object
                            3: Object
                         entity_id: "00145E5BB2641EE284F811A7907757A3"
                         entity_name: "Functional Areas"
                         entity_type: ""
    .....

The JSON object contains properties such as "entity_id," "entity_name," "entity_type," and "entity_children." The "entity_children" property can have multiple nested objects within it. My problem is how to iterate through all levels of these nested objects beyond just one level.

Here is a snippet of the raw JSON data:

{"root":   
    {"entity_id":"00145E5BB8C21EE286A007464A64508C",
     "entity_name":"TP_GTPAPI_TEST_BASE_ACC",
     "entity_type":"",
     "entity_children":
          [{"entity_id":"00145E5BB8C21EE286A007464A66508C",
            "entity_name":"TEST_CATALOG_GTPAPI",
            "entity_type":"",
            "entity_children":
                [{"entity_id":"00145E5BB8C21EE286A007464A66708C",
                  "entity_name":"Functional Areas",
                  "entity_type":"",
                  "entity_children":
                         [{"entity_id":"00145E5BB8C21EE286A007464A66908C",
                ......

If you have any suggestions on how to efficiently navigate through this JSON structure, please share your insights. Your help would be greatly appreciated.

From my understanding, your object includes a children property that consists of an array with objects of the same type. This essentially creates a hierarchical structure. To properly navigate through this object, you will require both iteration and recursion. Below is a sample code snippet that demonstrates the use of both techniques:


var data = {
    root: {
        a: "1",
        b: "1",
        c: "1",
        d: [{
            a: "1.1",
            b: "1.1",
            c: "1.1",
            d: [{
                a: "1.1.1",
                b: "1.1.1",
                c: "1.1.1",
                d: [
                    {
                        a: "1.1.1.1",
                        b: "1.1.1.1",
                        c: "1.1.1.1",
                        d: "1.1.1.1"
                    }
                ]
            }]
        }, 
        {
            a: "1.2",
            b: "1.2",
            c: "1.2",
            d: "1.2"
        }]
    }
};

function loop(obj) {
    for (var i in obj) {
        if (obj[i].d != null) {
            loop(obj[i].d);
            alert(obj[i].a);
        }
    }
}

function travel() {
    loop(data.root.d);
}
