About This Episode:
In this episode, we explore a superpower of JavaScript: higher-order functions — functions that can take other functions as inputs or return new functions as outputs.
🎯 What you’ll learn:
- What higher-order functions are and why they’re important.
- Functions as arguments with real-world examples using map, filter, and forEach.
- Functions returning functions to create flexible, configurable behaviors.
- A practical Pub/Sub pattern (publish/subscribe) — showing how higher-order functions enable reusable and event-driven code.
💡 Why it matters:
Understanding higher-order functions is a game-changer. They’re the foundation for functional programming patterns, modern libraries, and frameworks. Once you master them, you’ll start seeing opportunities to write code that’s cleaner, more modular, and easier to extend.
By the end of this episode, you’ll know how to bend functions to your will — letting them build, transform, and orchestrate other parts of your program. ⚡️
