How do arrays work?

Arrays work by storing multiple values in a single variable. Instead of creating a new variable for every value, you can group related values together in an array. This is especially useful when you have a list of items.

Here's a simple example:

const fruits = ["apple", "banana", "orange"];

In this example, fruits is an array that holds three values: apple, banana, and orange.

Here are some things that you can do with arrays:

• Access values using their index: fruits[0]

• Update values: fruits[1] = "mango"

• Add values: fruits.push("grape")

• Loop through values

Arrays are a basic but powerful tool in programming, and you’ll use them often when working with lists, collections, or structured data.
