Your filter function needs to return a value. I'm also guessing you want .length > 0 since there is no such thing as a string with a negative length. Finally, the filter method will return a new array, so you'll probably want to capture the result in a.

In the end, it would look something like this:

a = a.filter(function(x){return x.length > 0});
