Patterns in JavaScript
The word “patterns” in JavaScript usually refers to common, reusable ways of solving programming problems. These are often called design patterns.
A design pattern is not a ready-made piece of code. Instead, it is a general approach or structure that you can use when you encounter a particular type of problem.
For example, if many parts of your application need to use the same object, you might use the Singleton Pattern. If an object needs to notify many other objects when something changes, you might use the Observer Pattern.
Why do we need patterns?
As JavaScript applications become larger, simply writing functions and classes can become difficult to manage.
Patterns help you:
*Organize your code.
*Avoid repeating the same solution.
*Make code easier to maintain.
*Make communication between objects clearer.
*Separate different responsibilities.
*Make applications easier to extend.
*Provide commonly understood solutions to common problems.
Why Should We Use Patterns in JavaScript?
We use patterns because they give us proven ways to solve common programming problems.
Think of a pattern like a blueprint for building software. You don't have to reinvent the solution every time you face the same type of problem.
