The <strong>Array</strong> object lets you store multiple values
in a single variable. It stores a fixed-size sequential collection of
elements of the same type. An array is used to store a collection of data,
but it is often more useful to think of an array as a collection of
variables of the same type.
</p>
<h3>Syntax</h3>
<p>
Use the following syntax to create
an <strong>Array</strong> object −<br />
</p>
<pre
class="language-javascript"
tabindex="0"
><code class="language-javascript"><span class="token keyword">var</span> fruits <span class="token operator">=</span> <span class="token keyword">new</span> <span class="token class-name">Array</span><span class="token punctuation">(</span> <span class="token string">"apple"</span><span class="token punctuation">,</span> <span class="token string">"orange"</span><span class="token punctuation">,</span> <span class="token string">"mango"</span> <span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre>
<p>
The <strong>Array</strong> parameter is a list of strings or
integers. When you specify a single numeric parameter with the Array
constructor, you specify the initial length of the array. The maximum
length allowed for an array is 4,294,967,295.<br />
