Creating Arrays

We create an array by enclosing items in square brackets and separating them with commas. For example:

let shoppingList = ["Apples", "Chocolate", "Bread rolls"];

This creates an array with the elements "Apples", "Chocolate", "Bread rolls" and stores it in the variable shoppingList.

Arrays can store any data type — we can have an array that contains only one data type, or an array that contains different data types. For example:

let array = ["text", 123, true];

This array has three elements: "text", 123, and true. The first element is a string, the second element is a number, and the third element is a boolean type.
