All programs are composed of functions and data structures and the SOLID principles introduced by Robert C. Martin, help us group our code into modules and advise how to interconnect them. The goal of the SOLID principles is to build software structures like Lego blocks that can be easy to…

By employing clean architecture, you can design applications with very low coupling and independent of technical implementation details. That way, the application becomes easy to maintain and flexible to change. Clean architecture allows us to create architectural boundaries between dependencies which allows components to be intrinsically testable. What’s to follow…

There’s a real advantage in solving problems by delaying the implementation details as late as possible. It allows us to concentrate on business logic by turning the user stories into use cases. A user story is an informal, general explanation of a software feature written from the perspective of the…

Autocomplete or word completion works so that when the writer writes the first letter or letters of a word, the program predicts one or more possible words as choices. If the word he intends to write is included in the list he can select it. What will follow is my…

The promise of CSS was that we can drastically alter a site’s visual design without touching the HTML. As we do more front end development we realize CSS doesn’t quite live up to this promise. CSS plays a very important role in styling web applications. Best practice instructs us to…

Functional Programming is a programming paradigm where programs are constructed by applying and composing functions. So we give a function zero to many inputs and it returns one output. Exceptions are when something exceptional or out of the ordinary happens, like a “FileNotFoundException” from a file IO library and “undefined_column”…

Code can be said to be decoupled when your components are designed in such a way that they don’t depend on the concrete implementations of others. …
