Type-Parameters

An in-depth guide to Default Generic Arguments in TypeScript. Learn how assigning fallback types (<T = Default>) simplifies generic interfaces, combining constraints with defaults (<T extends Constraint = Default>), and enforcing strict parameter ordering rules.

An in-depth introduction to Generics in TypeScript. Learn how type parameters (<T>) bridge reusable logic with strict type safety, generic type inference, generic interfaces (ApiResponse<T>), and generic classes.

Before Go 1.18, writing a reusable function for finding a slice element required duplicate functions for int, string, and float64, or using reflection. Generics solve this using Type Parameters.
