Create Arrays in JavaScript

In JavaScript, arrays are resizable structures that can contain a mix of different data types ordered in a sequence.

Array literals are created using square brackets []:

array = [element1, ..., elementN];

Where:

• element1, ..., elementN are a list of optional values or variables separated by a comma character (,).

📚 In JavaScript, the value contained in an array is referred to as an element.

Example

In this example, the array assigned to the todo variable contains 0 elements:

let todo = [];

In this example, the array assigned to the grades variable contains 4 integer elements:

let grades = [3, 8, 7, 6];
