Custom Type

Definitions

1. A type defined by application code rather than provided directly by the language's built-in primitives. Custom types help model domain concepts explicitly and can enforce stronger invariants than loose generic structures.

   In plain English: A programmer-defined type used to represent something specific.

   Example: "Replacing raw strings with a custom type for customer IDs prevented several bugs caused by mixing tenant and account identifiers."
