What are some common design patterns in JavaScript?
Some common design patterns in JavaScript include Singleton, Factory, Module, and Observer patterns.
Can you explain the Singleton pattern?
The Singleton pattern ensures a class has only one instance and provides a global point of access to it.
How does the Factory pattern work?
The Factory pattern creates objects without specifying the exact class of object that will be created.
What about the Module pattern?
The Module pattern helps in encapsulating private variables and methods, exposing only what is necessary.
