Closures are functions that have access to variables from their outer scope even after the outer function has finished executing.
Closures are created when a function is defined within another function and has access to the outer function's variables.
They can access variables from the outer function even after the outer function has returned.
Closures are commonly used in event handlers and callbacks in JavaScript.
Event loop is a mechanism that allows JavaScript to perform non-blocking operations by handling asynchronous events.
Event loop is responsible for executing code, collecting and processing events, and executing queued sub-tasks.
