Anyone know a platform for developers to get their code reviewed

Have you ever started to learn a new language but want someone with experience to review what you’ve done to help ensure you’re doing things properly?

I’m a dev with 14 years behind me, I’m full stack with php for backend, I recently started learning node but with lack of knowing anyone doing node, to lay eyes on my code and say “why have you done this” or “don’t it this way, this is now the better way”.

I feel that there must be something out there where you can share some code and have someone experienced to help guide you or validate that you’re doing ok.

Stack overflow isn’t the right platform for this so does anyone know if one exists?
