// as we can be writable , enumerable and configurable are all set to false , it is hard coded to false and cannot be changed that is why the PI value is constant . 

// therefore we can also set our properties like this . and make it constant 

// let see another object to understand it better.

// console.log(descriptor2)
// as we can see the writable value and everything are set to true . so we can change the value . But if we set it to false then we won't be able to make any modifications to it . 

// in this step we will define the properties according to our wish .
// where we can fix it to constant . 
// though it is not suggested to make any property constant
