Understanding closures

In this section, we will understand closures from a C# perspective, and apply them to LINQ queries. Let's start with the definition of computer programming closures according to the content on Wikipedia.

Wikipedia: "In programming languages, a closure, also lexical closure or function closure, is a technique for implementing lexically scoped name binding in a language with first-class functions.

Operationally, a closure is a record storing a function together with an environment.

The environment is a mapping associating each free variable of the function (variables that are used locally but defined in an enclosing scope) with the value or reference to which the name was bound when the closure was created.

Unlike a plain function, a closure allows the function to access those captured variables through the closure's copies of their values or references, even when the function is invoked outside their scope."
