Tutorial August 30, 2024
javascript

JavaScript is a powerful and versatile programming language, and one of its most important features is the concept of closures. Closures enable you to create functions that have access to variables from their parent scope, even after the parent function has finished executing. This tutorial will guide you through the concept of closures in JavaScript, explaining how they work and providing examples of their practical applications.

A closure is a function that "remembers" the environment in which it was created. In JavaScript, closures are created every time a function is created. A closure gives you access to the outer function’s scope from an inner function. In other words, a closure is a combination of a function and the lexical environment within which that function was declared.
