I switched this year to working at a company who uses typescript for backend systems after working as a python dev for 3 years. It’s not that I hate it, it’s just that TS/JS does not give you anything in terms of built-ins. This testing suite is so fragmented, it’s this ugly thing that I dread working with. Anyone have advice for repos I can use that have rich testing frameworks? Or books? I’d love to learn to love TS, but it’s not there yet.
