I agree. We always put the little 'for loop that creates a list of functions that spit out the current number of the iteration' exercise first in all of our interviews.
Generally, when people solved that one fast, they also did well in the rest of the interview and if they struggled there, they also had a hard time coming up with an elegant solution for most of the other tasks.
What I also like about it is that a closure isn't the only way to solve it. You can use `let` for example to make sure the variables are block scoped, or use `bind` to partially apply a function with the number.
So in the end it's a conceptually very simple exercise that can give you a very good insight into how much the candidate knows about how JS actually works.
