I tend to judge the technical foundations of an open-source project by the programming language it is primarily written in.

From my experience, the highest quality implementations these days come either in Rust, Go, Clojure, Python, or TypeScript.

For older and well-established projects, it's usually C, C++, and Java.

I think what's important here, is not only the performance and the design of the programming language, but the entire ecosystem around it.

I am much more likely to rely on an open-source code that itself relies on high quality battle-tested dependencies.
