+## Wait there's more... The Javascript Client!
+If you loved the api style and architecture of flutter_janus_client and you wishing to have something similar for your next javascript project involving webrtc features.
+then worry not because we have got you covered. we have written wrapper on top of our good old `janus.js`, you might ask why? well the answer to that question is it does not support
+type bindings hence no rich ide support, so we proudly presents [typed_janus_js(feature rich promisified and reactive wrapper on top of janus.js)](https://github.com/flutterjanus/JanusJs)
+or you can straight away use it by installing from npm `npm i typed_janus_js`.
