🔹 Understanding TypeScript Generics | Beginner-Friendly Guide to Writing Reusable Code 🔹

In this video, I simplify one of TypeScript’s most powerful features — Generics. If you’ve ever repeated the same function for different data types or struggled to write flexible, reusable code, this tutorial will help you finally understand how generics work and why they matter. With real examples, clean explanations, and beginner-friendly visuals, I demystify everything from basic generic functions to constraints and practical use cases.

📘 In this complete tutorial, we break down the concepts:

Step-by-step, I take you through:
Why repetitive code becomes a problem
The identity function — the simplest example of generics
Understanding and type parameters
How TypeScript infers generic types automatically
Using generics with arrays, classes, and interfaces
How to constrain generics using extends
Real-world use cases where generics shine
Why generics make your applications more scalable and maintainable

🔥 What You’ll Learn:

What TypeScript generics are — and why they exist
How works in functions, classes, and interfaces
How to write a generic identity function
Type inference vs explicit type arguments
Generic use cases: arrays, boxes, pairs, and more
Using multiple type parameters.
Constraining generics with extends
How generics improve type safety and eliminate duplication
How generics help build scalable, reusable utilities

🎯 Perfect For:

Beginners learning TypeScript fundamentals
JavaScript developers transitioning to TypeScript
Frontend & backend engineers using React, Next.js, or Node.js
Students preparing for coding interviews
Developers tired of repetitive or brittle code
Anyone wanting to write flexible and type-safe applications
