When working with TypeScript, you quickly run into a common problem: 👉 You want your code to be reusable , but also type-safe . At first, it’s tempting to use any to make things flexible… but that comes at a cost: You lose type safety You lose autocomplete You introduce hidden bugs This is exactly the problem that TypeScript Generics solve. They let you write reusable code without sacrificing type safety . In this article, we’ll explore: What Generics are What problem they solve Practical examples you’ll actually use Best practices to avoid common mistakes Let’s dive in. 🤔 Problem with type reusability When you want your function to be reusable, you usually end up with this any approach: function identity ( value : any ): any { return value } It works but it also comes with problems such as no type safety, no IntelliSense, and can easily lead to break things.
