Closures in a for loop and lexical environment

Question

Simple case: I want to load several images which have a common name and a suffix, e.g: image0.png, image1.png, image2.png ... imageN.png

I\'m using a simple for loop

Answer 1

Since the variable i is declared outside the scope of the loop, it retains its final value after the loop has completed. The anonymous functions you're creating then all bind to this variable, and when they're called, they all get the same final value of N.

There's a good discussion of this in this question.
