After spending some weeks playing with Rust, I felt ready to test my skills and try some programming challenges in the Advent Of Code. My approach to tackle some of those challenges was to solve them using Javascript (I use it in my day to day) first and then port the code to Rust. While writing the port I just focus on getting the Rust code as elegant as possible to achieve that I research the Rust API's to get syntactically correct. It was after finishing porting this puzzle in particular and feeling a sense of accomplishment that I decided to test how the Rust compiled code will perform against Javascript interpreter.
