You can't believe from how much bugs TypScript has saved me. When it was "first released" (when it became more popular), I have ported our starter kit to TypScript and was amazed on how much stuff it was detecting as not safe.
Since then, I can't image working without TS. As for Third Party libraries, I have a different experience from other devs here, it works very well for most (if not all) big libraries/frameworks, and the autocomplete saves me so much time in digging in the docs.
