Ok, let's retry: this is exactly the point of TypeScript. Limiting human errors.

TS's goal is not to help the inexperient ones but, rather, to provide a more sensible and traversable data structure that serves the coders, either junior or senior ones, again, limiting human errors.

The fact that TS is an unquestionable success, although it requires time to be learned (not that much, but still) is, to me, very telling.
