What language(s) will you be using? Will you be trying anything different this year to usual?
My strongest languages, in no particular order, are Go, Python, JavaScript, and modern PHP (with types and all that jazz).
I’ve decided to go with JavaScript this year because over the last 15 years, they’ve been working on JavaScript like it’s the cure for cancer. They’ve added so much syntactic sugar to JavaScript in recent years, that I can develop solutions in fewer lines of code.
That said, for day one, I did separate implementations in JavaScript and Go. With Go, I leveraged the built-in support for testing, benchmarking, and profiling to look at the flame graph and figure out where I could optimize performance.
I’ve been wanting to learn both Rust and server-side Swift. I figure that during my time off over the holidays, I can practice porting my JavaScript solutions over to those other languages.
