## Why Use Functions?
Repeating code makes programs long and hard to maintain. Functions let you group commands into a reusable block, reducing repetition and making your code cleaner.

To **call** a function, simply use its name followed by parentheses, placing any required arguments inside those parentheses. For example, if you have a function named `greet` that takes a name of a person to greet, here is how you could call it:

```javascript
greet("Alice")
```
