The Zen of Ruby
A Simpler 'If'
You’ve seen the Ruby if
statement before:
if condition # Do something! end
If the “do something” is a short, simple expression, however, we can move it up into a single line (as you saw in the last exercise). The syntax looks like this:
expression if boolean
Ruby will expect an expression followed by if
followed by a boolean. The order is important. You can do this:
puts "It's true!" if true
but not this:
if true puts "It's true!"
It’s also important to note that you don’t need an end
when you write your if
statement all on one line.
Instructions
1.
Give it a go! Type a one-line if
statement in the editor to the right. It can be whatever you like.
