Like other programming language Ruby also have booleans data type for condition checking In Ruby only false and nil are falsey. Everything else is truthy (yes, even 0 is truthy).

condition checking here means using logical operators && , || , ! for example: 4 && 5 # This returns 5 nil && true # This returns nil true && nil # This returns nil true || nil # This returns true nil || "" # This returns ""

you just may have confused me more..ok so... anything dwtermined falsely or nil is valued less than 0. so -1 is falsely?? do logical operators vary from language to language
