Learn to collect data efficiently.

array_factory.js1 / 4

📦

Tutor: An Array in JavaScript is an ordered list of values. It is defined using square brackets `[]`. It is the most common way to group related data.

The List Builder

In JavaScript, an Array is a list-like object. Its syntax uses square brackets [] to wrap the elements.

Tip: Arrays in JS have "zero-based indexing", which means that the first element is at position 0.

Mission: Declare a constant called `list` that is an Array.
