What does modularity mean in programming

When you have multiple developers working on the same piece of code, it usually results in Git conflicts and various other issues which can be annoying and can slow down the team. You can also assign ownership to specific modules of code, ensuring teams are responsible for their part of the software, and enabling them to break the work down into smaller tasks.

The teams and modules come together with clearly defined interfaces and public APIs, ensuring everything fits together at deployment. Well, yes. The alternative to modular programming is usually to create a monolithic application of code, where all your code is more or less dumped into a single location.

These types of projects sometimes even reach the point where they need a structural overhaul, as they become too difficult to manage. So, even if your project starts out small, consider whether taking a modular approach from the beginning could help future-proof your code.

Certainly, if you expect your project to have a long life or to grow a lot, it might be good to consider modularity from the start, because structural overhauls can be very difficult, time consuming, and hard to fit in when there are features to be written. For example, there are many NPM libraries that only do one thing. And more and more developers are using frameworks that only do specific things, like Bulmer, which is a CSS framework that is fairly simple compared to some of the other popular CSS frameworks.

Category Engineering. Tagged Programming Principles. Functions are important because they allow us to take large complicated programs and to divide them into smaller manageable pieces. Because the function is a smaller piece of the overall program, we can concentrate on what we want it to do and test it to make sure it works properly. Generally, functions fall into two categories:. The main program must establish the existence of functions used in that program.

Depending on the programming language, there is a formal way to:. Program Control functions normally do not communicate information to each other but use a common area for variable storage. Specific Task functions are constructed so that data can be communicated between the calling program piece which is usually another function and the function being called. This ability to communicate data is what allows us to build a specific task function that may be used in many programs. The rules for how the data is communicated in and out of a function vary greatly by programming language, but the concept is the same.

The data items passed or communicated are called parameters. Thus the wording: parameter passing. The four data communication options include:.

The main program piece in many programming languages is a special function with the identifier name of main. Advantages of Using Modular Programming Approach —. Skip to content. Change Language.
