I was really stuck on how to incorporate them meaningfully, but I finally figured it out. Here's how I approached it using Python: from functools import reduce with open('… Re: Need Coding Help With A Project 1 Month Ago by Reverend Jim I don't know why you would use `reduce` and `lambda` when you could just do sum(numbers) And the directive >You should make use of two higher-order functions (i.e., map and reduce, or something else) to simplify the design. is self-contradictory as using `map` and `reduce` instead of `sum` does not simplify the design. It … Re: Any jQuery 4 users? 2 Months Ago by jkon I'm still using jQuery, a very slim build. Our JS library/framework handles all the heavy lifting, including AJAX, WebSockets, logical events, data manipulation, and architectural events.

I believe that Enzo only resurrected a 12 year old thread with the intent of spamming. You and I know that because, as moderators, we see in his profile his spamming attempts and his infractions.

This is because Javascript functions are "first-class objects" (see [URL="https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Functions"]here[/URL] for example).
