A JS developer will always use Array.forEach(callback) anyways - solving the problem without ever encountering it. yes, this stumbling block in JS is often mentioned.

But at least the article is written quite well.

Thanks a lot for clarifying this. I've caught myself striving with closures in js several times and never had the chance to realize that variables are function scoped, instead of block scoped.
