  1. What do arrays allow us to do?

The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type.

  1. What index should you use in order to access the first element in an array?

You will use ordinal numbers to access and to set values inside an array as follows.
[0] is the first element

1. An array is an object in which multiple values (elements) of the same type can be stored.

An array is like holding one physical wallet, where you can store multiple cash notes from the same national currency within it and pick which notes you want to use at a given point in time to spend at the store. This is more efficient than having separate wallets for different cash note denominations.

2. The first array listed is in position no. “0”.

So in order to access the first element use: name [0]

Example.

var firstname = [“Ivan”, “Filip”, “Frieda”]
names [0];
// --> “Ivan”

To access the first element in an array I need use the index 0, something like this:

let names = array('Ivan', 'Daniel');
console.log(names[0]);

Is it just a matter of memory? i rememberd matrixes long time ago. but forgot a lot

Probably a matter of memory… also, from our text, “The maximum length allowed for an array is 4,294,967,295”
