JavaScript coding patterns help you structure your code in a more maintainable and efficient manner. Here are some common patterns with examples and use cases:
1. Module Pattern:
โฃ The module pattern encapsulates code within an immediately-invoked function expression (IIFE) to create private scope and expose a public API.
โฃ Use Case: Encapsulating functionality and hiding implementation details.

2. Revealing Module Pattern:
โฃ A variation of the module pattern that explicitly returns an object literal, revealing only the parts you want to expose.
โฃ Use Case: Better control over the exposed API and improved readability.

3. Singleton Pattern:
โฃ The singleton pattern ensures a class has only one instance and provides a global point of access to it.
โฃ use Case: Managing a shared resource or providing a single point of access to a service.

4. Prototype Pattern:
โฃ The prototype pattern leverages the prototype chain to create objects by cloning existing objects (prototypes) instead of using a class.

โฃ Use Case: When you want to create objects without using a constructor function or to create objects with shared properties and methods.
That's a wrap!
