I came across this beauty:
def same_modality? list
check = list[0][0]
list.each do |i|
return false if check != i[0]
end
return true
end
This was “necessary” because I got an array of one-element arrays back, and I wanted to check whether or not that one element was the same across the array.
Three seconds of thinking made me realize that just maybe, I could do this:
list.uniq.size == 1
I -like- Ruby.
