How to create and clone a JSON object?

Question

I was wondering how can I create a JSON (JS) object and then clone it.

Answer 1

We can clone JSON object as below.

EmployeeDetails = 
{
  Name:"John Deer",
  Age:29,
  Company:"ABC Limited."

}

Now create one clone function

function clonning(Employee)
{
  // conversion from Object to String
  var EmployeeString = JSON.stringify(Employee);

  // conversion from String to Object type

  var EmployeeConvertedObject = JSON.parse(EmployeeString);

  // printing before changing prperty value.

  console.log(EmployeeConvertedObject);

  // modifying EmployeeConvertedObject property value 

  EmployeeConvertedObject.Name="Kelvin Bob";

   // printing After changing prperty value.

  console.log(EmployeeConvertedObject);

  // Now printing original json object.

  console.log(Employee);

  // Here original JSON object is not affecting. Only Cloned object affecting.


}

Now Call function.

clonning(EmployeeDetails);

Result:

clonning(EmployeeDetails)
VM212:22 {Name: "John Deer", Age: 29, Company: "ABC Limited."}
VM212:30 {Name: "Kelvin Bob", Age: 29, Company: "ABC Limited."}
VM212:34 {Name: "John Deer", Age: 29, Company: "ABC Limited."}
