Javascript Array Tutorial - push method
In the previous article we saw how to add one element at the end of the array. Javascrupt provides another way of adding an element at the end using the push method. So the statement
x.push ('Ford';)
does the same thing as
x[3] = 'Ford';
or the
x[x.length] = 'Ford';
Here is the complete example
<html>
<body>
<script type="text/javascript">
var x = ['toyota','honda','Audi'];
x[x.length] = 'Ford';
for (i=0; i<=3; i++)
document.writeln('x['+i+'] = '+ x[i]+ '<br />');
</script>
</body>
</html> |

It gives the following output
x[0] = toyota x[1] = honda x[2] = Audi x[3] = Ford
Advantage of the Push method
An advantage of the push method is that, you can add more than one element in a single statement. So, to add three cars at the emd, you could write.
x.push ('Ford', 'Hyundai','Volkswagon');
