Learn those JavaScript concepts from this page: https://www.pagser.com/joseph/js UPDATE (June 2022): As Arthur mentioned in the comments, there's still an issue in the events.js source code, and that quick fix will now regard all onceWrapper functions as the same thing. This will be problematic if we declare multiple once listeners with the same event name. If you take a look at the Node.js events.js file, you'll see how Node.js is handling those "once" functions. I'll post an update if I get the chance to fix this issue. I'll also appreciate it if you can share your solutions to the problem if you come up with one! -------------------------------------------------------------------- My LinkedIn Profile:   / joseph-heidari   Cododev Website: https://www.cododev.ca/
