Demystifying JavaScript Closures, Callbacks and IIFEs

[Jeff_Mott]

@felgall

A closure occurs when a variable or function defined inide of the inner function’s scope continues to be accessible to the outer function even after the inner function has returned. Just about the exact opposite of what you said.

Actually the article got it right. A closure is an inner function that has access to an outer function’s variables. And in fact the MDN article you referenced says the same.
