Code Sprout: Fundamentals of JavaScript Series - Tutorial #5: Functions

In this fifth tutorial of Code Sprout’s Fundamentals of JavaScript Series, we dive into functions—the building blocks of reusable, modular, and organized code.

Understanding functions is key to writing cleaner, more efficient programs. They allow you to define tasks once and use them again and again, reducing repetition and increasing clarity.

In this video, you’ll learn:

What functions are and why they matter in programming

How to write function declarations and expressions

How to use parameters and return values to pass and retrieve data

The power of callback functions and how they enable dynamic behavior

How to apply functions in real-world coding scenarios
