What is modularity? Dividing code into separate files? No! Hiding data? Well, up to a point… Protecting implementation details? Well, that’s a bit nearer the mark. But what does that really mean? How do you protect the implementation details of a module or an object? And why does it matter?
In this lesson, I look at some of the ideas and the history of modular programming. From Smalltalk to Modula-2, and onwards to C#, Ruby, Java and Object Pascal, I’ll try to explain what modularity is and why your code will be more reliable if you make use of it.
