Python is great for library orchestration and has tons of support for almost anything you need. So if you aren't building a large application and don't need concurrency, its great. Java is great for building large applications with large teams, since it limits how code is shared and how libraries are built, and has a culture of convention. Golang has greate concurrency support and meta programming support, so its awesome for web servers and plugging into systems that incorporate orchestration technologies. C++ and Rust are fast and efficient as hell when you need that. JavaScript is your only viable option when you need complex and interactive UI that's OS agnostic.
