Pros
  • Compiles Java bytecode to JavaScript and Java or Kotlin to WebAssembly GC
  • Maven and Gradle integration with JavaScript interoperability
  • Includes source maps, debugging, development servers, and browser testing
  • Compiles Clojure to JavaScript with Google Closure-compatible output and optimization.

  • Includes browser and Node.js REPLs, npm dependencies, macros, and source maps.
Cons
  • Works within TeaVM’s supported Java API constraints
  • Focused on new web applications and selected code reuse, not every Java workload
  • Requires self-hosted deployment
  • The toolchain is centered on Clojure rather than multiple source languages.
  • Its feature set may be more than needed for projects that only require JavaScript.
  • Support channels are documentation and community.
