JavaScript In The Database
If you wish to use the database's full potential rather than just its persistence layer you almost inevitably end up storing code together with data it processes. Performance, scalability, security, and many other aspects can benefit greatly from such an approach. In addition to Java and PL/SQL you can now use JavaScript as a server-side programming language.

Extend Node.js application with GraalVM
Run the GraalVM with Node.js by replacing V8 with GraalVM for executing JavaScript. It enables polyglot applications (for example, use Java, R, or Python libraries) running Node.js with large heap configurations and Java's garbage collectors, or using GraalVM's interoperability to define data structures in C/C++ in order to use them from JavaScript.

Build serverless apps with Node.js
Serverless functions-as-a-service technologies, such as the open source Fn Project, let developers focus on code without worrying about infrastructure concerns such as scaling, patching, and high availability. Fn Project supports Node.js—one of the most popular runtimes for developing serverless functions-based applications. Upload your Node.js function code and let Fn Project execute it in response to events.
