I’ve always wondered how event-driven programming worked – it is very different from the programming paradigms I was taught in school. I was confused by the asynchronous nature of callbacks and promises. It was also interesting to me how something like setTimeout or setInterval was implemented! It seemed non-trivial for this to be implemented in another language like C/C++ without constantly checking a timer in several areas of your code.

This weekend I decided I would learn a bit of Rust and try to understand the hype around it! Like learning most programming languages, I started out writing a "Hello World!" program.
