Ruby - Check if a particular element in the array starts with a String : So I have this array `a` with values such as `['___', 'abc', 'def']`

How can I check if `a[0]` starts with `"___"` ?

I have something like this `a[0].start_with?("___")`, but I get an error.

I am running Ruby 2.1.8

Cheers!
