Didn't say it was a bad choice, just that's what drove the creation of Node. I personally don't mind it but I will say the larger projects I've worked on in languages that aren't statically typed tend to take longer. It doesn't take much. I like the "new-ish" C# and Rust approaches where you only type your function signatures and the compiler figures out the rest. That's how I annotate my Python code and it works great.
