*** Conditional Statements ***

These statements return booleans.

&& means and returns true only when both sides are true [5] pry(main)> (1 < 3) && (4 < 5) || mean or returns true if either side is true => true

unless = if not e.g. if user != admin is the same as unless user = admin

##If Statement##

If (true) desired action elsif (true) desired action else default action if none are true end ALSO written as . . . desired action if true

case (or switch statement): another way of writing if...elsif

```ruby
puts "Hello, there.  What's your name?"                         \n
name = gets.chomp                                               \n
case name                                                       \n
when "tom"                                                      \n
  puts "hello sexy."                                            \n
when "fred"                                                     \n
  puts "oh, hi fred. :/"                                        \n
else                                                            \n
  puts "who are you and why are you using my computer?"         \n
end                                                             \n
```

anyone want to explain == vs =?###

== is a boolean operator - it evaluates if two things are equal or not and returns "true" or "false". I see == and think "is equal?" = is an assignment operator - it assigns the value on the right to the variable on the left.
