What is a "closure"?
A closure is the combination of a function enclosed with references to its surrounding state (lexical environment)....

That insideoutaide then outside we inside gave me a headache. Im going to bed lol. Jk, great stuff. Thanks for helping me understand it a little more as well. 😁
Haha sorry! I thought the naming was kinda funny, but I can see how it might be confusing 🙈
Lol I was just kidding.
Thank you for the article.
I had always been using the concept, but never called it a "closure". I have it in my mind as a "function wrapper". It allows all my inner wrapped functions (and at times do have a lot of them) to use all the common variables I have already declared in the main outer function without having to pass them individually to each function and declare them again.
Are multi-level closures classified as something else or just call something like "nested closures"?
I'm honestly not sure 🤔 that might get more into specific scope than closure itself. But, for instance, let's say in my "inside outside" example, there was a local scope variable inside of
inside, that would be inside the "closure" created by theinsidefunction. But I'm not sure if there's any kind of special term for that in terms of closures.Closures have always broken my brain a little bit 😅, but this explanation makes it quite clear! Thank you for sharing 😄.
Thank you Sandrico! I'm so glad this helped clear things up for you 🤗
I aways thought this concept was called a Factory pattern.
I've never heard that term before 🤔 I guess I'll have to look it up
Great explanation..Closures always confuse me..
