Patterns

Patterns are a set of instructions used to create a product or solve a problem. They are often used in software engineering to create a reusable solution to a common problem.

Patterns is a software engineering concept that was first introduced by Christopher Alexander in the late 1960s. It is a way of organizing and structuring software code in a way that is both efficient and easy to understand. Patterns are used to create reusable solutions to common problems in software development.

Patterns are based on the idea that software should be organized in a way that is both easy to understand and maintain. This means that the code should be organized in a way that is easy to read and understand, and that it should be organized in a way that makes it easy to modify and extend. Patterns are also designed to be reusable, meaning that they can be used in multiple projects without having to be rewritten.

Patterns are organized into three main categories: creational, structural, and behavioral. Creational patterns are used to create objects, structural patterns are used to organize the code, and behavioral patterns are used to define the behavior of objects. Each of these categories has its own set of patterns that can be used to solve common problems in software development.

Patterns are an important part of software engineering, as they provide a way to structure code in a way that is both efficient and easy to understand. By using patterns, developers can create code that is easier to maintain and extend, and that is more efficient than code written without patterns. Patterns are also reusable, meaning that they can be used in multiple projects without having to be rewritten.
