Design patterns provide proven development paradigms for modeling real-world challenges in code. Learning patterns prevalent in JavaScript allows writing more flexible, reusable, and organized codebases.
Let’s explore what design patterns are along with several fundamental JavaScript patterns that deliver maintainable code structuring. Understanding these patterns will level up your architecture skills!
What Are Design Patterns?
Design patterns provide templates for handling programming challenges without having to reinvent the wheel each time. They capture development wisdoms for clean interfaces and extendable code:
For example, the Iterator pattern standardizes traversal of aggregate objects like arrays to make them more iterable, while the Strategy pattern encapsulates interchangeable algorithms allowing improved flexibility.
Patterns originate from common programming hurdles and expert solutions to eloquently tackle them. Learning existing patterns will improve code quality through good design principles and organization.
