Closures are a fundamental concept in many programming languages, particularly those that support first-class functions. At a high level, a closure is a function that "remembers" the environment in which it was created. This means it has access to variables from its outer (enclosing) function's scope, even after the outer function has finished executing. This unique characteristic allows for powerful programming patterns and is a cornerstone of functional programming paradigms. For those new to programming, imagine a function as a recipe; a closure is like a recipe that also comes with a snapshot of the specific pantry (the variables and their values) that existed when the recipe was written down. Even if you take that recipe to a different kitchen, it still knows about the original pantry's ingredients.
