PLJS – JavaScript for Postgres
PLJS is a new, modern JavaScript trusted language extension, bundling QuickJS, a small and fast JavaScript runtime with Postgres, providing fast type conversion between Postgres and JavaScript, fast execution, and a very light footprint. Here are bencharks that show how it compares to PLV8: https://github.com/plv8/pljs/blob/main/docs/BENCHMARKS.md This is the first step toward a truly light-weight, fast, and extensible JavaScript runtime embedded inside of Postgres.

In plain words
PLJS is a JavaScript language extension for PostgreSQL that bundles QuickJS, a lightweight JavaScript runtime, directly into the database. It enables developers to write stored procedures and functions in JavaScript with fast execution, efficient type conversion between PostgreSQL and JavaScript, and a minimal footprint. The extension is designed as a modern alternative to existing solutions, offering improved performance and efficiency for JavaScript workloads within PostgreSQL databases.
