How to remove empty element in an array

L

Li Chen

Hi all,

I have an array of [1,2,''] I want change it to [1,2]. I check the
document about Array but I cant't find a way to remove the empty
element. Any comments?

Thanks,

Li

It's "[1, 2, <empty-string>]"? If so, then it's not an empty element.
If you have [1, 2, nil] then you can just use Array#compact or
Array#compact!. Otherwise, look at #delete_if.
