In our last lesson, we saw how we can make all the required fields in a type to be optional. Here we learn the opposite i.e. how to make all the optional fields to be required with the help of Required.
Instructor: [00:00] As you can see here, we don't have age and gender in our user object. It is not throwing any errors because both of the fields are optional in our type.
[00:08] With the help of required, we can make all our option fields to be required. Now, if I put required here in our user type, it would make the age and gender to be required also. It will throw the error that age and gender are required.
[00:19] Now, if I put the age here and gender here, the error will go away.
