Advanced JavaScript Tutorial for Experienced Developers
JavaScript uses automatic memory management, which means that the developer doesn't need to manually allocate or deallocate memory. The JavaScript engine's garbage collector (GC) is responsible for reclaiming memory that is no longer in use by the application.
Garbage collection in JavaScript is primarily based on the concept of reachability. An object is considered "reachable" if it can be accessed or is referenced from the root, which is usually the global object (window in browsers).
Understanding Closures in JavaScript: A Comprehensive Guide
Closures are essential because they enable powerful and flexible programming techniques. They allow you to:
- Encapsulate private data: Closures can help you create data that cannot be accessed directly from outside the function.
- Create factory functions: Closures can generate functions with specific behaviors or data preloaded.
- Maintain state across function calls: Closures allow you to maintain and manipulate the state of variables across multiple function calls.
