                    <h2>Arrays</h2>
                    <p>
                        Arrays are ordered, number-indexed collections of any object or in short, a list. Arrays are used to store 
                        things (objects) in an ordered list such as a list of songs, a list of students in a classroom, or a list 
                        of keystrokes a user clicks. Here are some examples of arrays:
                    </p>
                    <ol>
                        <li><code class="ruby-code">[ ]</code>
                            <ul>
                                <li>This is an empty array</li>
                            </ul>
                        </li>
                        <li><code class="ruby-code">[5]</code></li>
                        <li><code class="ruby-code">["hello", "world"]</code>
                            <ul>
                                <li>This is an array with two objects separated by the comma.
                                    <code>hello</code> is on index 0 and <code>world</code> is on index 1</li>
                            </ul>
                        </li>
                        <li><code class="ruby-code">["hello", 1, 2, 3, true, false, [address, "san francisco"]]</code></li>
                    </ol>
                    <p>
                        Arrays are enclosed in the [ ] brackets, separated by the commas and the first index starts with 0 (zero) 
                        then 1, 2, 3, etc. Arrays are very useful in keeping track of an ordered list of things.
