Question

I have below json which has a node careerLevels and this contains inner child elments.

input = {
            "careerLevelGroups": [
                {
                    "201801": 58,
                    "201802": 74,
                    "careerLevel": "Analyst",
                    "careerLevels": [
                        {
                            "201801": 29,
                            "201802": 37,
                            "careerID": "10000100"
                        },
                        {

                            "201801": 29,
                            "201802": 37,
                            "careerID": "10000110"
                        }
                    ]
                },
                {

                    "201801": 58,
                    "201802": 74,
                    "careerLevel": "Consultant",
                    "careerLevels": [
                        {

                            "201801": 29,
                            "201802": 37,
                            "careerID": "10000080"
                        },
                        {

                            "201801": 29,
                            "201802": 37,
                            "careerID": "10000090"
                        }
                    ]
                }
]}

i need to remove all the careerLevels node dynamically from this json and only display below json.

output= {
            "careerLevelGroups": [
                {
                    "201801": 58,
                    "201802": 74,
                    "careerLevel": "Analyst"

                },
                {

                    "201801": 58,
                    "201802": 74,
                    "careerLevel": "Consultant"

                }
]}

I have tried to use

let strippedJson = copyObject(mergedJson);
    delete strippedJson.careerLevels; // remove careerLevels but this is not doing anything.

I think i need to use something like :

input.forEach(element => {element.delete}) // something like this

I answered, hope it will work as per the expectation. Thanks. — Rohìt Jíndal

You can try following code:

let output = JSON.parse(JSON.stringify(input));
output.careerLevelGroups.forEach(group => delete group.careerLevels);

Use array Map method to iterate the careerLevelGroups array and then delete the careerLevels property of an object :

var jsonObj = {
	"careerLevelGroups": [{
			"201801": 58,
			"201802": 74,
			"careerLevel": "Analyst",
			"careerLevels": [{
					"201801": 29,
					"201802": 37,
					"careerID": "10000100"
				},
				{

					"201801": 29,
					"201802": 37,
					"careerID": "10000110"
				}
			]
		},
		{

			"201801": 58,
			"201802": 74,
			"careerLevel": "Consultant",
			"careerLevels": [{

					"201801": 29,
					"201802": 37,
					"careerID": "10000080"
				},
				{

					"201801": 29,
					"201802": 37,
					"careerID": "10000090"
				}
			]
		}
	]
};

var res = jsonObj.careerLevelGroups.map(obj => {
delete obj.careerLevels
return obj;
});

console.log(res);
