I do realize that I can do
unless [1].empty? But I'm wondering if there is a method?

nil? will only return true if the object itself is nil. That means that an empty string is NOT nil and an empty array is NOT nil. Neither is something that is false nil. => NilClassnil.
Checking array is empty method in Ruby. The empty? method returns true if a array is empty; otherwise, it returns false . Similarly, we can also use the length method to check for an empty array in Ruby.
empty? is a String class method in Ruby which is used to check whether the string length is zero or not. Syntax: str. empty? Parameters: Here, str is the given string which is to be checked.
As well as #any? as davidrac mentioned, with ActiveSupport there's #present? which acts more like a truth test in other languages. For nil, false, '', {}, [] and so on it returns false; for everything else true (including 0, interestingly).

You may use [1].any?, which is actually defined in Enumerable
Note that this will not work in case your array hold only nil or false values.
