Devan Patel has written a good tutorial about 4 Javascript Design Patterns that we should know!

Every developer strives to write maintainable, readable, and reusable code. Code structuring becomes more important as applications become larger. Design patterns prove crucial to solving this challenge – providing an organization structure for common issues in a particular circumstance.

JavaScript web developers frequently interact with design patterns, even unknowingly, when creating applications.

Although there is a diverse list of design patterns used in certain circumstances, JavaScript developers tend to use some patterns customarily more than others.

In this post, I want to discuss these common patterns to expose ways to improve your programming repertoire and dive deeper into the JavaScript internals.

The design patterns in question include the following:

Module

Prototype

Observer

Singleton

Each pattern consists of many properties, though, I will emphasize the following key points:

Context: Where/under what circumstances is the pattern used?

Problem: What are we trying to solve?

Solution: How does using this pattern solve our proposed problem?

Implementation: What does the implementation look like?
