/* Lesson 2 using of interface

 in the above example if you see the types i.e :{id :number,name :string ,age :number}
 we have to do this again and again now in order to save ourselves from this hectic typing Interface comes in

defining interface  */
/*you can define interface like this and now ill show you how to do the previous coding in a simpler way
  now as you see we have defined our type easily and we dont have to define it like this :{id :number,name :string ,age :number}  */

which will return the object and and aslo defined the type with it */
