Description: The function scope refers to the context in which a function is defined and the variables it can access. In programming, each time a function is created, a new scope is established that encapsulates the local variables of that function. This means that variables defined within the function are not accessible from outside it, helping to avoid naming conflicts and keeping the code more organized and modular. Function scope is fundamental to understanding how variables are managed in various programming languages, including JavaScript, Python, PHP, and TypeScript, among others. Additionally, it allows for the creation of nested functions, where one function can be defined within another, creating an additional scope. This concept is crucial for both object-oriented programming and functional programming, as it allows for encapsulating behaviors and data, facilitating code reuse and the creation of more complex and maintainable applications. In summary, function scope is an essential feature that influences how programs are structured and executed, affecting the visibility and lifecycle of variables within the code.
