JRuby vs Rust: What are the differences?

JRuby: A high performance, stable, fully threaded Java implementation of the Ruby programming language. JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java. The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information; Rust: A safe, concurrent, practical language. Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.

JRuby and Rust belong to "Languages" category of the tech stack.

"Java" is the top reason why over 7 developers like JRuby, while over 81 developers mention "Guaranteed memory safety" as the leading cause for choosing Rust.

JRuby and Rust are both open source tools. It seems that Rust with 37.3K GitHub stars and 5.85K forks on GitHub has more adoption than JRuby with 3.32K GitHub stars and 830 GitHub forks.

According to the StackShare community, Rust has a broader approval, being mentioned in 39 company stacks & 105 developers stacks; compared to JRuby, which is listed in 13 company stacks and 4 developer stacks.

    What are some alternatives to JRuby and Rust?
    Ruby
    Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.
    Groovy
    Groovy builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. It makes modern programming features available to Java developers with almost-zero learning curve.
    Rails
    Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.
    Go
    Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
    PHP
    Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

    How developers use JRuby and Rust

    Marc3842h uses RustRust

    Rust is used in Shirogane (https://github.com/Marc3842h/shirogane).

    Shirogane is a osu! beatmap mirror built for shiro. We use Rust because of memory safe but still low level and high performance.
