JavaScript Functions — The Simplest Visual Explanation
Understanding JavaScript becomes so much easier when you can see how it works.
This slide breaks down a function into three simple steps:
➡️ Input — calling the function
➡️ Processing — running the code
➡️ Output — returning the result
Just like a mini machine, a function takes something in, does the work, and gives something back.
Perfect for beginners, students, or anyone starting their coding journey. 🚀
