What are some common JavaScript design patterns?
Some common JavaScript design patterns include the Module Pattern, Singleton Pattern, Factory Pattern, and Observer Pattern.
Can you explain the Module Pattern?
The Module Pattern is used to encapsulate private variables and functions, exposing only the public API. It helps in organizing code.
What is the difference between the Factory Pattern and the Singleton Pattern?
The Factory Pattern creates objects without specifying the exact class, while the Singleton Pattern ensures a class has only one instance.
Can you give an example of the Observer Pattern?
Sure! The Observer Pattern allows an object (subject) to notify other objects (observers) about changes in its state, like a news agency notifying subscribers.
