For security I make Apparmor profiles for each script. I think the module system and NPM is what made Node.JS popular. And personally I like function passing style aka. callbacks, Promises and async/await looks more terse but is actually more complicated and prone to errors. I also don't like that TypeScript extend the JavaScript language and ads a compilation step to it, it's much better to add doctype like comments and you would get the best of both worlds, although I don't think type-checking is needed if you already do testing. For me static typing is mainly for performance, like in Dart, you can't simple make JavaScript more performant without it. With TypeScript you have "performance optimization" but without the performance benefit. If your code needs type annotations for others to understand what it does you need to use better names. The type annotations are for the compiler. Auto-complete and parameter hinting can be done via inference. And public parameters and methods should have documentation.
