In the book “Eloquent JavaScript,” is there an explanation of how parameters function as local variables within functions? Understanding this concept is crucial for grasping function scopes.
Absolutely! Parameters in JavaScript, including those mentioned in “Eloquent JavaScript,” are essentially local variables created when a function is called. This means they exist only within the function’s scope and are initialized with the values passed during the function invocation. This setup ensures your functions can process data without interfering with variables outside its scope. If you’re diving into function scopes, exploring how parameters become local variables is a key piece of the puzzle. Hope this clears things up!
