JoC #19: Class methods vs instance methods

      If can keep your head when all about you are losing theirs it’s just possible
      you haven’t grasped the situation.
            — Jean Kerr

Today, we’ve got some background stuff to discuss. Not much happening in terms of new functionality to our project, but important (and, no doubt, incredibly interesting) conceptual information.

Why is there sometimes a classname before a method call and sometimes a variable?

I’m sure all of us have had sleepless nights where we’ve been lying awake pondering this question. Today, it shall be answered!

Even if you’re not that interested in discussion of underlying concepts, but just want to GET STUFF DONE — still, watch this video. You can only become a good programmer (and get stuff done) if you understand what you’re doing.

I really want you not only to copy what I’m showing you, but become able to invent and create your own programs. For this, it’s important to get the concepts.

So, hit start, sit back for a few minutes, and learn something!

Concepts discussed: internal method calls, external method calls, static methods, instance methods
