In PHP I can do like:
$arrayname[] = 'value';
Then the value will be put in the last numerical key eg. 4 if the 3 keys already exists.
In JavaScript I can’t do the same with:
arrayname[] = 'value';
How do you do it in JavaScript?

You can use the push method.
For instance (using Firebug to test quickly) :
First, declare an array that contains a couple of items :
>>> var a = [10, 20, 30, 'glop'];
The array contains :
>>> a
[10, 20, 30, "glop"]
And now, push a new value to its end :
>>> a.push('test');
5
The array now contains :
>>> a
[10, 20, 30, "glop", "test"]

To add multiple elements at the same time or to add an element somewhere other than the end check out the answer: stackoverflow.com/a/12189963/984780

Just to help other rookies who come along, do NOT try
a = a.push('test'); for 10 mins. :)You can use
arrayName.push('yourValue');
OR
arrayName[arrayName.length] = 'yourvalue';
Thanks
