<p>The equality operator returns Boolean <code>true</code> if both operands are the same (type and value). Arrays and objects are checked for deep equality. Arrays must have the same values in the same order. Objects must have the same key/value pairs (order is not relevant). Otherwise it returns <code>false</code>.</p>
<p><strong>Examples</strong></p>
<ul>
<li><code>1+1 = 2</code> => <code>true</code></li>
<li><code>"Hello" = "World"</code> => <code>false</code></li>
</ul>
