interface{} is used to accept any value of x

type any in go in an alias of interface{}

reflect.ValueOf() takes in any argument and return a new reflect.Value type

The reflect.Value type has many methods that let you inspect and modify the value it represents

some methods of reflect.Value

NumField() :

func (v [Value](<https://pkg.go.dev/reflect#Value>)) NumField() [int](<https://pkg.go.dev/builtin#int>)

it return the number of fields in the value which helps us to iterate over the fields

Field(i int):

func (v [Value](<https://pkg.go.dev/reflect#Value>)) Field(i [int](<https://pkg.go.dev/builtin#int>)) [Value](<https://pkg.go.dev/reflect#Value>)

Field returns the i'th field of the struct v. It panics if v's Kind is not Struct or i is out of range.
