The Liskov substitution principle ensures that subclass objects can be used interchangeably with those of the superclass, preventing unexpected program errors. Adhering to this rule simplifies code management and increases predictability.

This article explains the Open-Closed Principle (OCP) of SOLID design, which advises creating flexible and maintainable code by keeping classes open to extension but closed to modification. It uses an example to show how to adhere to the OCP by defining an interface and creating separate classes for each shape.

Astro is an innovative static site generator that focuses on static generation instead of JS framework. But, how much better is it?

The Single Responsibility Principle (SRP) is a design principle promoting maintainable code. It states that each class should have only one job. This post explains its importance with code examples, resulting in more understandable and maintainable code.

The Singleton pattern restricts a class's instantiation to one object, providing benefits such as global state, configuration settings, and simplified testing. It enforces a single point of access for the instance of the class and reduces the amount of code needed to maintain a single instance of an object.

Learn the SOLID principles of OOP: SRP, OCP, LSP, ISP, and DIP. These guidelines help create flexible and easy-to-understand software designs, avoiding common problems.
