Fix as many errors in the following JavaScript code as you can:

// Create an array of names
var names = array("Peter", "Paul", "Mary");

// Display a list of the names:
echo(<ul>);
for (var i=o; i<names.count, j++) {
	echo '<li>' . names[i]):
}
echo </ul>

// Append a name to the list of names:
names.append("Lemon Tree');
