Functions In TypeScript | TypeScript Master Class | Toaster Code
🚀 Welcome to Episode 5 of the TypeScript Masterclass by Toaster Code!
In this video, we’re mastering *functions in TypeScript* — the heart of your application.
By the end, you’ll know exactly how to type parameters, define return types, write arrow functions, and handle callbacks like a pro (and without letting `any` ruin your day).
We’ll cover:
✅ Typing function parameters and return values
✅ `void` functions and explicit vs implicit typing
✅ Optional & default parameters
✅ Arrow functions and their syntax
✅ Function expressions and typing function variables
✅ Callbacks with strict boundaries
✅ Functions as types in interfaces
✅ Common mistakes to avoid
💡 Whether you’re building a small project or a massive codebase — typed functions will save you from debugging nightmares.
👻 Bonus: If your callbacks are messier than your group chat at 3 a.m., this episode is your intervention.
