Introduction to Design Patterns in Vanilla JavaScript

Design patterns play a crucial role in software development, offering established solutions to frequent design challenges. These patterns don’t give us ready-made code but offer time-tested concepts we can adapt to handle recurring themes and complexities more effectively.

In recent years, the landscape of web development has changed significantly. Some older patterns might not be as useful as they once were, while others have evolved to address the unique needs of modern development, especially with the rise of frameworks like React. React’s component-based approach and features like Hooks have influenced how we apply traditional patterns and even sparked the creation of new ones. As React has grown to be the go-to library in the JavaScript ecosystem, its influence on design patterns has reshaped best practices for building maintainable, scalable applications.

This guide will introduce you to both classic JavaScript design patterns and modern adaptations for React, covering essential patterns, their advantages, and potential drawbacks. Through this, you'll gain a solid understanding of how to use design patterns to streamline and optimize your JavaScript and React code for today’s web applications.
