1. Scope refers to the accessibility of a variable. If a variable is created outside of a function its scope is considered
   to be global which means it can be accessed by any function in the javascript file. Global variables can even be accessed
   by other linked Javascript files as long as the file with the global variable is loaded first. Variables that are created
   in a function are considered to have local scope which means they can only be accessed within the function they were created
   in. When a local scope variable is created that has the same as a global scope variable, the local variable will take 
   precedence over the global variable and not affect the global variable.
   
2. Global variables are avoided in Javascript because they can lead to unintended results. When more than one function uses 
   or alters a global variable it risks the outcome of the functions being not what is expected. One function might assume
   a global variable has a certain value when in fact another function has
