create JSON key of second level to lowercase in javascript / nodej s-CodePudding

I am trying to make json key to lowercase so I got a solution where it making all the json key toLowercase but I don't want to make all the json key to lower case I only want to make the second level of json key to the lowercase

so while doing console.log(data) I am getting this output

{
  'valueToBeAssign': {
    titleAsName: 'random title',
    urlOrWebsite: 'www.google.com',
    name: 'english',
    number: 123
  }
}

{
  'computerAssignTask': {
    taskName: 'debug every thing',
    issueGenerated: 'At low level',
    assigneName: 'Mick',
    reporterName: 'Pete',
    issueResolve: 'not yet'
  }
}

so I wrote a code

          let json = JSON.stringify(data);
          var newJson = json.replace(/"([\w] )":/g, function ($0, $1) {
            return '"'   $1.toLowerCase()   '":';
          });
          var newObj = JSON.parse(newJson);
          console.log(newObj);

but by this I am getting all the key in lowercase

{
  'valuetobeassign': {
    titleasname: 'random title',
    urlorwebsite: 'www.google.com',
    name: 'english',
    number: 123
  }
}

{
  'computerassigntask': {
    taskname: 'debug every thing',
    issuegenerated: 'At low level',
    assignename: 'Mick',
    reportername: 'Pete',
    issueresolve: 'not yet'
  }
}

what I actual want is the first key should not be changed but after that it should be changed like this

{
  'valueToBeAssign': {
    titleasname: 'random title',
    urloOrwebsite: 'www.google.com',
    name: 'english',
    number: 123
  }
}

{
  'computerAssignTask': {
    taskname: 'debug every thing',
    issuegenerated: 'At low level',
    assignename: 'Mick',
    reportername: 'Pete',
    issueresolve: 'not yet'
  }
}

I want it in this format

CodePudding user response：

It might be better to iterate through all the keys of the object. That way, you can discriminately alter the keys by level.

const data = {
  'valueToBeAssign': {
    titleAsName: 'random title',
    urlOrWebsite: 'www.google.com',
    name: 'english',
    number: 123
  }
}

const newData = {}
for (const key of Object.keys(data)) {
  newData[key] = {}
  for (const innerKey of Object.keys(data[key])) {
    newData[key][innerKey.toLowerCase()] = data[key][innerKey]
  }
}

console.log(newData)
