Upload your .rb file, select JavaScript as the output format, and click 'Convert'. The tool instantly processes your Ruby code and provides a downloadable .js file that you can use in any JavaScript environment.

Why should I convert Ruby (RB) to JavaScript (JS)?

Ruby is typically used for server-side logic, while JavaScript runs natively in browsers and Node.js. Converting RB to JS lets you reuse the same code on the frontend or in serverless functions, reducing backend dependencies and improving web app performance.

How does the RB to JS converter handle Ruby-specific syntax and gems?
