How do closures enable Callbacks

Callbacks: Closures are frequently employed as callback functions. Callbacks are functions passed as arguments to other functions, and they're executed at a later time or upon a specific event. Closures can capture variables from their surrounding context, making them useful for customizing behavior in asynchronous operations.
