Etymology

The concept of closures originated in the field of computer science, specifically in programming languages that support nested functions. The idea of capturing the environment in which a function is defined dates back to the early days of functional programming. As programming languages evolved, closures became a fundamental feature in languages like Lisp, Scheme, and eventually JavaScript. The use of closures has since spread to many other programming languages, becoming a widely used technique for creating encapsulated and modular code.
