How do I convert Scala code to JavaScript using LetsConvert?

Paste your Scala source code into the input editor, select Scala as the source and JS as the target, then click Convert. The converter processes the code through a Scala compilation pipeline and outputs portable JavaScript, preserving method signatures and control flow. You can copy the generated JS or download it as a .js file directly.

Why should I convert Scala to JS instead of using Scala.js?

If you need to migrate legacy JVM Scala code to a pure JavaScript environment without adding a compiler plugin or runtime, this converter provides a one-time, dependency-free translation. It's useful for reusing business logic in browser extensions, serverless functions, or Electron apps where a Java runtime isn't available. Unlike Scala.js, it produces readable, editable JavaScript rather than minified compiler output.

How does the converter handle Scala's pattern matching and immutable collections?

Pattern matching is translated into switch statements or nested conditionals, depending on the scrutinee type. Options become null-checked values or sentinel objects, and immutable collections like List, Map, and Set are mapped to native JavaScript arrays, Maps, and Sets. The conversion preserves the original semantics but uses idiomatic JS constructs. JVM-specific features like reflection or classloaders are flagged in the comments.

Is SCALA-TO-JS free to use?

Yes, SCALA-TO-JS on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! SCALA-TO-JS works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?
