Answer 2

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).

Answer 3

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 ""

Answer 4

what does condition checking mean?? when will I use it or when would it come up??

Answer 5

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
