for JS/TS, it supports the postman execution (for Enterprise)
for JVM ecosystem, it supports gPRC (for Enterprise)
it’s up to your project stack anyway.

WebSocket, SSE and MQTT (Enterprise) are also currently only supported in Java/Scala. We’ll add JavaScript support for these if there’s enough demand for it.

Postman will always be JavaScript only as it’s the language Postman uses for pre-request and pros-request scripts (that we’re working on supporting).
