Request you to please help in building a function in javascript to obtain the mentioned output from the input given.

INPUT : An object (possibly a nested object)

example :

{

"message":"string" ,

"data1": {

    "Output1": {

        "leaf1": "abc",

        "Leaf2": "123"

    }

}

"data2": {

    "Output2": {

        "leaf3": "abc",

        "leaf4": "123"

    }

}  

}

OUTPUT : An array of string

Example : str= ["message", "data1.Output1.leaf1", "data1.Output1.leaf2" , "data2.Output2.leaf3","data2.Output2.leaf4"]

Something like this it will work

const getBranches = (data, prefix=[]) => {
  if (typeof(data) !== 'object') {
    return prefix.join('.')
  }
  return Object.entries(data).flatMap(([k, v]) => getBranches(v, [...prefix, k]))

  }

  const data = {
    "message": "string",
    "data1": {
      "Output1": {
        "leaf1": "abc",
        "Leaf2": "123"
      }
    },
    "data2": {
      "Output2": {
        "leaf3": "abc",
        "leaf4": "123"
      }
    }
  }


console.log(getBranches(data))
