In this JavaScript tutorial, we explore closures, a concept that allows inner functions to access variables from their outer functions even after the outer function has finished execution. Closures help maintain state and can be used for creating private variables in JavaScript. In this example, we define a function outer() which contains a variable count. The inner() function returned from outer() is able to access and update count even after outer() is done executing. This is the power of closures! Watch this video to see how closures work and why they are so useful for data encapsulation.
