  Do-notation for JavaScript

I haven’t tried this out myself but there’s libraries out there that emulate do notation with generators, if that’s any better than e.g. fp-ts’ Do. A quick Google search led me to burrido

  A fully type-safe and lightweight way of using exceptions instead of throwing errors

I one also thought that handlong errors works better when havung a good structure but that didn't really plan out. I stopped throwing anything inside my codebases. The only way to get full knowledge over the possible outcomes of a function call is if the function also returns exceptions instead of throwing them. TypeScript will not help you if something gets thrown. I wrote my own little library to handle this: https://github.com/ivanhofer/exceptionally I recently discovered that there are also other solutions out there that do something similar. With such an approach you will also know after 5 and more levels of function calls if your code really covers all possible outcomes. Really useful for refactoings!
