Expanding your JavaScript skills: Tackling nested object key and value replacements

I am looking to manipulate the values of a nested object using JavaScript. The structure of the object is outlined below.

let jsonObj = {
    "service":[
        {
            "name":"restservice",
            "device":"xr-1",
            "interface-port":"0/0/2/3",
            "interface-description":"uBot testing for NSO REST",
            "addr":"10.10.1.3/24",
            "mtu":1024
        }
    ],
    "person": {
    "male": {
      "name": "infinitbility"
    },
    "female": {
      "name": "aguidehub",
      "address": {
           "city": "bbsr",
           "pin": "752109"
      }
    }
  }
}

In the above example, I want to find and replace specific values within the nested object. Specifically, I need to locate all instances of the key name and update the value to BBSR. With three occurrences of the name key in the object, I will use JavaScript to perform these replacements.

Answer №1

If you are looking to implement a thorough search algorithm, consider using the deep search method.
Start by looping through the entire object and analyzing each property individually.
Check if the current property is an object or an array.
If it is, continue to recursively iterate over that property.
If the property is a simple value (not an object or array), check if its key matches 'name'.
If the key does match 'name', execute your desired action.
If not, move on to the next property.
Follow this structured approach to efficiently navigate through complex data structures.

const deepSearch = (target) => {
    if (typeof target === 'object') {
        for (let key in target) {
            if (typeof target[key] === 'object') {
                deepSearch(target[key]);
            } else {
                if (key === 'name') {
                    target[key] = 'xxx'
                }
            }
        }
    }
    return target
}
