Type vs Interface in TypeScript: When to Use Each

💡 Type vs Interface in TypeScript — what's the real difference? Both type and interface help you define the shape of data in TypeScript, but they shine in slightly different scenarios: // Interface interface User { name: string; age: number; } // Type type UserType = { name: string; age: number; }; So when to use which? 👇 ✅ Use Interface When you expect it to be extended or merged later. Great for designing reusable object shapes and contracts. ✅ Use Type When you need unions, intersections, or advanced type manipulations. Perfect for complex data structures and utility types. Example: type Status = "loading" | "success" | "error"; ⚡ Pro tip: Interfaces are open (can be merged), while types are closed (fixed once defined). 👉 In modern TypeScript, both work almost interchangeably — so use what makes your code more readable and consistent! #TypeScript #WebDevelopment #Frontend #ReactJS #CodingTips #SoftwareEngineering

Great summary. I typically use interfaces for structured models and types when working with unions or more complex compositions. Both tools complement each other well.
