Design patterns are high-level answers to problems that we as software engineers encounter frequently. It isn’t code — I repeat, IT IS NOT CODE. It’s akin to explaining how to approach these issues and come up with a solution.

I got 99 problems but design patterns aren’t 1

One of the most common things I’ve found is that people who graduate in computer science or another IT-related field where design patterns were taught — but never sufficiently trained to use them either — forget about them or find them of no use in their software development career.

They are, nonetheless, core abilities that all developers should have, mainly because as your software development career progresses, you will be expected to recognize patterns and utilize them to construct microservices/ systems/solutions.

There Are Several Reasons Why Design Pattern Will Be Beneficial To You.

Simply put, design patterns are used to make the task easier.

— For instance, when writing a program, the primary rule of an object is that all attributes must be private and cannot be accessed by other classes. So, how can we make our code more readable and adaptable? You can utilize the Creational Design Pattern to clean up your code.

— Another reason is that design patterns establish a shared vocabulary that you and your colleagues may use to communicate more effectively. You can remark, "Oh, just use a Singleton for it, though," and everyone will comprehend your advice. If you already know the pattern and its name, there’s no need to explain what being a singleton is.

I have researched many design patterns, and I’ve used some of them in personal and work projects.

So, in this piece, I’ll share my top three design pattern recommendations, all of which are simple to learn and use in your work/personal projects.

So, get a cup of coffee and enjoy reading!

1. Strategy Design Pattern

He probably needs a design pattern!

This is my favourite design pattern of all time.

This pattern enables you to switch between techniques for a specific task at runtime without the client knowing it. Rather than implementing a single method directly, the code is given runtime instructions that tell it which of the group of algorithms to run.

The “Open-Closed design principle,” which argues that base code should be open for extension but closed for modification, was one of the vital principles I learned about in my fourth year of university (which I’m sure many of you have heard of).
