  "ID": 2,
  "NAME": "Anbu",
  "Salary": 80000 
},
{
  "ID": 3,
  "NAME": "Bala",

}  ]}

I want to move the array item 2 to up or down. the expected output is like below.

{  "EmployeeLists": [
{
  "ID": 2,
  "NAME": "Anbu",
  "Salary": 80000
},
{
  "ID": 1,
  "NAME": "Anand",
  "Salary": 90000
},
{
  "ID": 3,
  "NAME": "Bala",
  "Salary": 85000
} ]}

Answer 1

You can swap the 2 elements like so:

var x = EmployeeLists[2];
EmployeeLists[2] = EmployeeLists[1];
EmployeeLists[1] = x;
