How do most computer languages evaluate and make simple decisions? Mostly through the use of the conditional 'If' statement. Whats more Ruby is no different though a lot might argue including myself a hell of a lot easier. So lets take a look at this statement in action shall we?
irb(main):001:0> age = 50
irb(main):002:0> if age < 50
irb(main):003:1> puts('still a few years on the clock yet')
irb(main):005:1* puts('too bad')
First off we set assigned 50 to the age. Then we started with the conditional 'if' to evaluate the age where we used an operator < which means less than. So we said if age was less than 50 print the first message or if not print the second message.
And that's a simple way to use the conditional 'if' operator in Ruby.
