 Sometimes a block of code should only be run under certain conditions. Flow control – via `if` and `else` blocks – lets you run code if certain conditions have been met.

 In order to use flow control successfully, it's important to understand which kinds of values are "truthy" and which kinds of values are "falsy." Sometimes, values that seem like they should evaluate one way actually evaluate another.

 ## Conditional Variable Assignment with the Ternary Operator

 Sometimes a variable should be set depending on some condition. An `if`/`else` statement works, but in many cases the ternary operator is more convenient. The ternary operator tests a condition; if the condition is true, it returns a certain value, otherwise it returns a different value.
 
 The ternary operator:
+
 ```
-// set foo to 1 if bar is true;
-// otherwise, set foo to 0
+// Set foo to 1 if bar is true; otherwise, set foo to 0:
 var foo = bar ? 1 : 0;

 Rather than using a series of `if`/`else` blocks, sometimes it can be useful to use a `switch` statement instead. `switch` statements look at the value of a variable or expression, and run different blocks of code depending on the value.
