Gleam's standard library supports both targets: Erlang and JavaScript.

This library is compatible with all versions of Erlang/OTP 26 and higher, as well as all NodeJS, Deno, Bun, and major browsers that are currently supported by their maintainers. If you have a compatibility issue with any platform open an issue and we'll see what we can do to help.
