Hi, AFAIK in Ruby the only (or the "coolest") way to do something as:
if num in [1,2,3,4]
is by doing:
if [1,2,3,4].index(num)
Is it? any other "cooler" way? Thanks.
Well not saying this is actually a good idea, but...
class Object
def in(collection)
collection.include? self
end
end
if num.in [1,2,3,4]
...
end
.
