First of all, JavaScript is not Java. It has nothing to do with Java (The language and its associated technologies from Sun Microsystems). To be honest, I'm not even sure why it's called JavaScript.

Its top 10 were JavaScript, Python, Java, PHP, C#, CSS, C++, TypeScript, Ruby, C, and Swift. Rust was in 19th spot. Notably, though, Java was not one of the languages to see much growth on GitHub.
