What are Design Patterns? Where are they used?

Hello friends, in this article, we will examine design patterns together.

Design patterns can be described as accepted general solutions to common problems that have emerged during the process of coding. Design patterns are explanations or templates for how a problem can be solved.

At this point, it is entirely possible to create our own solutions, but using a design pattern will provide us with both an accepted solution and a more understandable code structure. Let’s explain with an example: for instance, if a new person joins your project and you are using your own solution, it will be easier for them to adapt to a project that has been accepted by a certain community and has many available resources.

Why do we need design patterns?

Using a standard solution will increase the readability and reusability of the code in large-scale projects. Using an accepted solution to problems will speed up the development process. It prevents complexity and makes your code simpler and more meaningful. Design Pattern Categories

Creational Patterns: Responsible for the creation of objects in our application. These are design patterns that attempt to appropriately create objects. Structural Patterns: Design patterns that determine how multiple classes will behave when performing a task together. Behavioral Patterns: Design patterns that analyze the interactions between objects during runtime of our application. Design patterns are generally found under these categories. I plan to explain the popular patterns under these headings in my next article along with examples in the Go language. Let’s end our article by explaining the patterns we will cover in the upcoming articles.
