Day 15 of my MERN stack journey. I studied functions today.

I stopped copying and pasting code. I learned to package logic into reusable blocks.

Here is what I learned:

• Functions are code blocks. They run when you call them.
• Parameters are placeholders in the declaration.
• Arguments are the real values you pass in.
• The return keyword sends a value back. It stops the function.

I practiced with these projects:

• Sum and product functions for math.
• A vowel counter. It scans text and counts vowels.

Next, I will study arrow functions and array callback methods like .forEach().

Do you use traditional functions or arrow functions in your work?
