A function takes in inputs, does something with them, and produces an output.
First you declare a function using var, and then give it a name sayHello. The name should begin with a lowercase letter and the convention is to use lowerCamelCase where each word (except the first) begins with a capital letter.
Then we use the function keyword to tell the computer that you are making a function.
The code in the parentheses is called a parameter. It's a placeholder word that we give a specific value when we call the function.
Then write your block of reusable code between { }. Every line of code in this block must end with a ;.
Exp of the code.
