Using the object destructuring assignment as a parameter

Just like the array destructuring assignment, we can also use the object destructuring assignment as a function parameter. The following example demonstrates this:

   function myFunction({name = 'Eden', age = 23, profession =                        "Designer"} = {})   {
     console.log(name, age, profession); // Outputs "John 23 Designer"
   }
   myFunction({name: "John", age: 23});

Here, we passed an empty object as a default parameter value, which will be used as a default object if undefined is passed as a function argument.
