Generic Constraints

What is Generic Constraints?
Generic constraints in TypeScript allow you to limit the types that can be used as type arguments for a generic type or function. They ensure that the type argument satisfies a specific requirement, like having certain properties or methods. This provides more type safety and enables you to work with specific properties of the generic type, knowing they are guaranteed to exist.
