Comment on Ask HN: Is it worth it to invest in learning TypeScript?parentComments−Zababa4ywithout strict compile time type checking that typescript affords writing correct javascript programs is almost impossible.It's tedious but it's far from impossible.−friedman234yWithout an automated system telling you where to add checks for possible undefined values I think it's actually impossible in practice.−Zababa4yI think it is very possible. There's a simple technique for that: check everything, all the time. As I said, it's tedious but it's far from impossible. You can probably optimise it by checking less things in practice.
