Enhancing Classes in JavaScript Using Closures

The article discusses the concept of closures in JavaScript, an essential feature of the language. A closure is a mechanism that allows functions to access their lexical scope even after the function has finished executing. The author explains that every function in JavaScript creates its own closure, enabling it to maintain information even after the function's execution. A simple example is provided to illustrate how closures work and their practical applications. Understanding closures is crucial for developers who want to leverage JavaScript's full potential and improve their coding efficiency.
