[Tutor] creating classes while coding

[Japhy Bartlett]

I think OOP makes it easy for new programmers to set up programs, and
it can make for some pretty neat English looking code, but a more
functional approach generally makes for much leaner, faster performing
code.

I find them most useful when you have several functions that might
need to share some variables that the rest of the program doesn't care
about, especially if you might need to load that information at
run-time.

Just my two cents though, this is mostly a personal style thing, if
your code works. :)
