Apache Dubbo-js 4.0.0 released

After long-term community feedback and collaboration, and thanks to the efforts of the vivo open source collaboration team, we finally ushered in the release of apache dubbo-js 4.0.0.

dubbo-js 4.0.0 will be a new milestone. We have made major software architecture adjustments and provided full-stack dubbo service capabilities. The dubbo/dj under construction will help the framework code zero development ability by building a cross-language DSL language for dubbo.
