How to convert Kotlin to JavaScript
- 1. Paste your Kotlin code into the left editor above. Whole files work — not just snippets.
- 2. Confirm the languages. Source is set to Kotlin and target to JavaScript. Open Advanced to preserve comments or switch to the advanced model.
- 3. Click Convert and copy the JavaScript result, or run it in the compiler to confirm it behaves.
Why convert Kotlin to JavaScript?
Teams port Kotlin to JavaScript when migrating a codebase, sharing logic across services, or learning how a familiar program maps onto a new language. Doing it by hand is slow and error-prone — subtle differences in syntax, typing, and standard libraries are easy to miss. Port My Code handles the mechanical translation so you can focus on reviewing the result.
Frequently asked questions
Is the Kotlin to JavaScript converter free?
Yes. You can convert Kotlin to JavaScript for free with rate-limited usage. Upgrade to Pro for unlimited conversions, the built-in compiler, and the advanced model.
Will the converted JavaScript code actually run?
Port My Code produces idiomatic JavaScript using standard libraries and correct types. For anything non-trivial, review the output and run it in the compiler before shipping.
Can I convert a whole file, not just a snippet?
Yes — paste as much Kotlin as you like. Free requests have a size limit; Pro removes it.
