I work in a team where we use C# for our backends and React/TS for our frontends. And of course a lot of other stuff, like Docker, Terraform, Azure etc. I would very strongly encourage anyone who suggested introducing different tools in our project, not to do that. Not because I don't enjoy learning, but because it's a waste of time. I don't need to learn Rust, C# works fine. I don't need to learn Vue, React works fine. I don't see any value in learning yet another tool to do the same job, I'd much rather spend my time getting actual work done and getting better at using the tools we're already using.
