 Strings and numbers may be our building blocks, but as your scripts get more complex, you're going to need a way to deal with large quantities of them. Luckily, JavaScript has a couple of data types that are used for just that. An Array is an ordered collection of items (strings, numbers, or other things).

 1. Read through JavaScript.info's [array method guide](https://javascript.info/array-methods) for a deeper look at some further array methods in JavaScript. Again, you do not need to do the exercises at the end of the page; we will come back to these later.

This is where you'll find all built-in array properties and methods and their documentation. This will likely be something you regularly revisit as you code and solve problems.
