Define the basic building blocks that tell GraphQL what kind of values your API accepts and returns.
Scalars represent individual values in GraphQL. The standard scalar types include String, Int, Float, Boolean, and ID, and GraphQL uses them to validate the values flowing into and out of your API.
Real applications often need values that do not fit neatly into the built-in scalars, such as dates, timestamps, or custom identifiers. GraphQL allows you to define custom scalar types with your own parsing and serialization rules.
