технически (In programming languages, closures are a technique for implementing lexically scoped name binding in languages with first-class functions. Operationally, a closure is a record storing a function together with an environment: a mapping associating each free variable of the function, in other words, variables that are used locally, but defined in an enclosing scope, with the value or storage location to which the name was bound when the closure was created. A closure – unlike a plain function – allows the function to access those captured variables through the closure's reference to them, even when the function is invoked outside their scope.
