JavaScript Tutorial | First-Class & Higher-Order Functions | Chapter 12 | Part 12

Welcome to Part 12 of our complete JavaScript tutorial series! In this video, we explore First-Class Functions and Higher-Order Functions (HOFs) — one of the most powerful features of JavaScript. You will learn: What first-class functions are and how JavaScript treats functions like values How to assign functions to variables, pass them as arguments, and return them from other functions Higher-order functions (HOFs): functions that take other functions as arguments or return functions Built-in HOFs: map(), filter(), reduce(), forEach() with practical examples Using rest (...args) and spread (...array) with HOFs Arrow functions as concise HOFs Common quirks and pitfalls to avoid when working with functions 💡 Practice exercises included: Passing functions as arguments Functions returning functions Array manipulations using map, filter, reduce Using rest & spread operators Arrow function HOF examples By the end of this video, you’ll understand how to write cleaner, reusable, and powerful JavaScript functions and use higher-order functions to make your code more efficient and readable. ✅ Chapter Highlights: First-class functions → treated like values Higher-order functions → take or return functions Built-in HOFs → map, filter, reduce, forEach Rest & spread operators → flexible arguments Arrow functions → concise HOF usage Avoid common function pitfalls 🔔 Don’t forget to like, share, and subscribe for the complete JavaScript tutorial series!
