vIn programming we often need to use various constants, e.g.
RGB combinations, the number of steps to take in a squiral, etc.
vIt is good programming practice to give names to these, rather
than embedding the constants in your code.
vAdvantages:
oPutting them at the beginning of your code makes it
easier to find and change them.
oIf you use the constant in several places and want to
change it, there’s just one place to change.
