 ## Choosing Between Variables and Constants
 
-When should you use a variable, and when should you use a constant? A variable should be used when a value might change during the course of a single run of a program. For example, when you start running a program, your favorite may be Jon Snow, but perhaps by the end of the program's run, you may want to switch your allegiance to another character. A constant, on the other hand, is a way to bind a name to a value that won't change. This lets you refer to that value using a label without being concerned with the exact value that label takes.

For example, when you start running a program, your favorite may be Jon Snow, but perhaps by the end of the program's run, you may want to switch your allegiance to another character (like when you changed the value of `favoriteCharacter` to "Tyrion Lannister"). A constant, on the other hand, is a way to bind a name to a value that won't change. This lets you refer to that value throughout your program where you are certain without a doubt that the value will _never_ change.
