Question 4 - the definition of a closure is incorrect #90

Open vibecode opened 4 years ago

I believe the definition of a closure as "a function defined inside another function..." is not particularly correct. A closure is a function + lexical environment it's bound to. It doesn't necessary require an outer function.

You're right, I like Kyle Simpson definition much more after I read his books. May I ask you to create a pullrequest?
