Programming is actually a very unstructured activity. Way before all these automated encapsulations, people have been writing basically 0 and 1 to do compliex operations. And since most of the new code platforms support certain backward compatibility, there are more and more ways of doing the same thing. It’s kind of like Lego. You can use any pieces to put together a castle, as long as it looks like a castle, and it doesnt fall apart then you cant really say it isnt a castle.

It’s a problem everybody is facing in this domain. It’s hard to maintain uniform design. And that is how you know programming is as much an art as well as a science. And all the examples flowing around on the Internet in a way make things worse.
