What is a practical use of closures in JavaScript?
- Encapsulation
- Inheritance
- Code Reusability
- Memory Management
Closures in JavaScript are often used for encapsulation. They allow variables and functions to be "enclosed" within a function, preventing them from polluting the global scope and providing a level of data privacy. This enables code organization, reduces naming conflicts, and promotes modularity in your programs. Closures are a key feature in achieving encapsulation in JavaScript.
