Actually committing this time:

Checkpoint 1:
A value is something that is unchangable, however a name is just
a pointer, or a reference for a velue. The value that is assigned to
a name can be changed.
Variables are useful for when you want to keep track of something
that has a value which can be changed. They are also helpful for
creating general programs that can solve the same problem with a
different input for the variable.

Checkpoint 2:
A function is like a variable in that it doesn't always have the same
value, and doesn't always provide the same result.
Functions are useful in breaking down big problems, by deconstructing
the big problem into different parts and figure out how to accomplish
each part. One example is if you want to draw several houses. first
you could write a function for each part of the house, such as a window,
door, etc. Then write a drawHouse function which draws the house where
you want it, and then lastly, you can just use the drawHouse function
wherever you want a new house in the picture.
