Generic Constraint
Explore how to apply generic constraints in TypeScript to ensure your generic classes and functions only accept types extending specific interfaces. Understand how this improves type safety by allowing access to certain properties while preventing invalid types. This lesson helps you write more reusable and error-resistant code by leveraging constrained generics.
We'll cover the following...
With generic, you can specify that the type passed into your generic class must extend a specific interface. Generic allows having code that can rely on a minimal interface without forcing a specific class.
For example, with a list, you do not need to force the list to hold a specific object. Instead, you can create a generic list where the generic type passed must extend a definition.
