-Flow Control allows the excution of code only under certain conditions.
+Flow Control allows the excution of code only under certain conditions. In Ruby, we used case statments, if statments, if/else statements, if/elsif/else statements, ternary operators, and case statements to control what code runs when. JavaScript has similar methods to control what blocks of code to execute: if statements, if/else statements, if/else if/else statements, ternary operators, and switch statements.

-`if` statements can also be combined with an `else if` clause. This is like an else statement, but with its own condition. It will only run if its condition is true, and the previous statement's condition was false.

+The ternary operator is used as a shortcut for the `if-else` statement. You've probably seen it before in Ruby looking something like this:
+
+```ruby
+cart = ["graphic t-shirt", "aluminum water bottle"]
+
+puts cart.empty? ? "Please add something to your cart." : "You're ready to check out." 
+
+# Above prints:

+// Wow, that eliminates all the best foods! :( 
+// Sounds like you're an omnivore.

+// Why????
+// Because no breaking statement is found it executes all of the cases after the true case (which is case 1)
