That's a JavaScript function, I know all about those. But wait...what's that asterisk for? Why does that function look different from that function? Is there a difference? And when does this mean that and not this? Let's take a deep dive into JavaScript functions, find out all the little quirks and intricacies and hopefully walk away with a better understanding of the functions we're writing, and maybe how to write them better. In this talk you'll learn about the importance of `this`, other variables specific to functions and what to look out for when coding JavaScript functions in general.
