In jQuery, the param() method is used to serialize an array or object of key-value pairs into a query string format that can be appended to a URL or used in an AJAX request. This method is particularly useful when you need to send data to a server using HTTP GET or POST requests, as it formats the data in a way that is commonly accepted by web servers.

The param() method creates a serialized representation of an array or an object.

Example 1

$(document).ready(function(){
  personObj = new Object();
  personObj.firstname = "yogesh";
  personObj.lastname = "hadiya";
  personObj.age = 21; 
  $("button").click(function(){
      console.log($.param(personObj))
  });
});

if you run example 1 then you will find output like below :

firstname=yogesh&lastname=hadiya&age=21

Example 2

$(document).ready(function(){
  personObj = new Object();
  personObj.firstname = "yogesh";
  personObj.lastname = "hadiya";
  personObj.age = 21; 
  $("button").click(function(){
      console.log(personObj)
  });
});

if you run example 2 then you will find output like below :

{firstname: “yogesh”, lastname: “hadiya”, age: 21}
