Chapter 10. Arrays > Deconstructing an Array

Deconstructing an Array

As stated earlier, an array is a data type that can hold multiple pieces of information. Here's an easy way to imagine this: A variable is like a chair, and it can hold one person (one piece of data). On the other hand, an array is more like a bench, it can hold multiple people (multiple pieces of data).

Each piece of data in an array is called an element. Each element is automatically assigned the name of the array and a unique number called its index, which is enclosed in brackets. However, the first element in an array is not assigned the number 1; it is instead assigned the number 0 because arrays are zero-indexed meaning that they start counting at zero instead of one.
