Loop through a nested JSON object

Question

I'm looking for a solution to loop through a nested JSON object in pure JS. Indeed I'd like to console.log every item and each of its properties.

const json_object = 
{
    "item1":{
        "name": "apple",
        "value": 2,
    },

    "item2":{
        "name": "pear",
        "value": 4,
    }
}

for(let item in json_object){
    console.log("ITEM = " + item);

    for(let property in json_object[item]){
        console.log(?); // Here is the issue
    }
}

Answer 1

You are accessing an object's value using its key in json_object[item] so just keep drilling down into the object.

for(let item in json_object){
    console.log("ITEM = " + item);

    for(let property in json_object[item]){
        console.log(json_object[item][property]);
    }
}

 const json_object = { "item1":{ "name": "apple", "value": 2, }, "item2":{ "name": "pear", "value": 4, } }; for(let item in json_object){ console.log("ITEM = " + item); for(let property in json_object[item]){ console.log(`key:${property}, value:${json_object[item][property]}`); } }
