## Challenge: In Your Own Words
Scope refers to the regions of your code in which your variables can be accessed. If a variable is within
the global scope, it means that it can be accessed from any other place in your program. If a variable is
local to a function, that means that it can only be accessed by the code inside the block of that function.

Global variables are avoided because they can cause all kind of unintended side effects. These side
effects can cause parts of your program to produce different results when given the exact same inputs,
which is obviously not a good thing.

Strict mode forces the user to be more careful with their syntax by throwing errors where the code
would normally just run. Things such as: if a function parameter name were not unique within whole of the
