I found on this link how to create arrays with a chosen number of zeros.
[Most efficient way to create a zero filled JavaScript array?](https://stackoverflow.com/questions/1295584/most-efficient-way-to-create-a-zero-filled-javascript-array)

But my question is, imagine i already have a array 

```
var a = ['hihi','haha']

```

how can i add 12 zeros after my two first elements ? So that it becomes : 

```
a = ['hihi','haha',0,0,0,0,0,0,0,0,0,0,0,0];

```

of course I could go for a 

```
for(var i = 0; i < 12, i++){
  a.push(0);
}

```

but is there a one line method ? something like 

```
a.push(6*[0]);

```
