JavaScript Design Patterns - Introduction

What is a Design Pattern?

A pattern is a reusable solution or a template that can be applied to commonly occurring problems in software design.

Why patterns are important?

Design patterns have three main benefits:

1.     Patterns are proven solutions
2.     Patterns can be easily reused
3.     Patterns can be expressive

Patterns provide a solution scheme, not exact solution for the problem. Patterns don’t solve all design problems nor do they replace good software designers, however, they do support them.
