Why You Should Never Use any in TypeScript (Do This Instead)

Description

Using any in TypeScript might feel like a shortcut, but it’s one of the fastest ways to break your backend code without realizing it. In this short video, I explain why professional TypeScript developers avoid any and what you should use instead to write safer, cleaner, and more predictable code. The moment you use any, TypeScript stops protecting you. You lose autocomplete, type safety, and early error detection — and your backend slowly turns back into plain JavaScript. This is one of the most common mistakes beginners and even intermediate developers make when building APIs, services, and microservices. In this Short, you’ll learn when to use types, interfaces, and Zod schemas, and how these simple changes can instantly improve your developer experience and reduce production bugs. This advice applies whether you’re building Node.js APIs, microservices, or full-stack TypeScript applications. If you want to level up your backend skills with real-world best practices — not theory — this is exactly the kind of habit you should fix early. 👉 Subscribe for daily backend and TypeScript tips 🔗 @codewithjay #typescript #backenddevelopment #nodejs #webdevelopment #programming #codingtips #softwareengineering #cleanarchitecture #zod #developers #codewithjay
