Design Pattern
Design patterns are reusable, general solutions to common problems that occur in software design. They provide templates for structuring code to improve flexibility, maintainability, and scalability, without being tied to specific programming languages or frameworks. Examples include Singleton, Observer, and Factory patterns, which help developers avoid reinventing solutions for recurring design challenges.
Developers should learn design patterns to write cleaner, more efficient, and more maintainable code, especially in complex applications where scalability and team collaboration are critical. They are essential in object-oriented programming for structuring systems, reducing bugs, and facilitating communication among developers by providing a shared vocabulary for design solutions.
