Parameters: This method accepts a single parameter as mentioned above and described below:

• URL_Query: This method takes a URL Query String to convert.

console.log("The generated JavaScript Object is : ",s);

Output:

The generated JavaScript Object is :  
{ 'https://example.com/path/to/page?name': 'ferret', color: 'purple' }
