I have an array that I need to remove spaces from, for example it returns like 

`[book, row boat,rain coat]`

However, I would like to remove all the white spaces.

All the guides I saw online said to use `.replace`, but it seems like that only works for strings. Here is my code so far.

```
function trimArray(wordlist)
{
    for(var i=0;i<wordlist.length;i++)
    {
        wordlist[i] = wordlist.replace(/\s+/, "");
    }

}

```

I have also tired `replace(/\s/g, '');`

Any help is greatly appreciated!
