The basic conditional if in ruby is like any other programming language.
if condition then
[statements to execute if condition is satisfied (true) ]
end
If only a statement needed to executed then we can use shorthand form of if. Statement is at front followed by if and condition.
Ruby also have unless for conditional branching. Difference is statement will be executed if condition not satisfied (false).
Try it yourself at irb ! Bye …
Ruby programming language have constant like other language we know ? Or Ruby dont have ?
Ruby have naming convention related to variable names. If a variable name begin with upper case then its considered constant. Ruby wont stop you to change that constant, it only emit warning like a test case below on irb.
So thats Ruby’s constant.
