How to iterate through a JSON schema and setting all the values to an empty string?

Question

I'm trying to iterate through a JSON schema object which have many nested properties.

{
    "schema": {
        "type: "object",
        "properties": {
            "nestObj1": {
                "type: "object",
                "properties": {
                    "nestObj12": {
                        "type":string
            "nestObj2": {
                "type": "object",
                "properties": {
                    "nestObj22": {
                        "type": "object",
                        "properties": {
                            "nestObj23": {
                                "type": "string"
    }
}

I want to turn the above into this

{
    "nestObj1": {
        "nestObj12": ""
    },
    "nestObj2": {
        "nestObj22": {
            "nestObj23": ""
        }
    }
}

I feel like recursion would be best to do this, but I just can't think of how to recursively go through the entire thing and creating key value as we go along. nestObj will stop when the type is a string and will continue if it is an object type.

To do what you are wanting recursion is definitely a good way to do. Heres an example that would work with what you have provided

 function generateDataFromSchema(schema) { if (!schema) { return } if (schema.type === 'string') { return '' } const parsedData = {} Object.keys(schema.properties).forEach( (item) => { parsedData[item] = generateDataFromSchema(schema.properties[item]) }) return parsedData } const dataToParse = { schema: { type: 'object', properties: { nestObj1: { type: 'object', properties: { nestObj12: { type: 'string' } } }, nestObj2: { type: 'object', properties: { nestObj22: { type: 'object', properties: { nestObj23: { type: 'string' } } } } } } } }; console.log(generateDataFromSchema(dataToParse.schema))
