Is TypeScript better than Python?
In terms of raw performance, Typescript is much faster than Python. When coding memory-intensive tasks in Python, e.g games, that utilize high-end 3D graphics, the CPU begins to take a hit and there is a significant drop in performance. Unlike Typescript, Python is not asynchronous at its core.
Is TypeScript good for backend?
All in all, there are use cases for backends where TypeScript is a great fit, e.g. Serverless Functions or Microservices. However, there are limitations to be aware of like the single threaded runtime and the potential need to rewrite parts of the app due to changing APIs of dependencies.
Is TypeScript a waste of time?

Is TypeScript similar to C#?
Typescript isn’t a direct upgrade from C#, though — it’s still fundamentally javascript at the core (one way of ‘compiling’ a typescript file is to just strip out all the typescript-specific annotations and ship what’s left) so there are always going to be some points where the types don’t line up quite right, or …
