Dogelog Player is a Prolog system that is 100%
written in Prolog itself. Previously only tested
with node.js, we produced a release that is able
to run on the newly available Bun command line
JavaScript engine. bun.js itself is realized with
the novel programming language Zig.

To use bun.js we fixed a programming error in that
we replaced our operating system success test by
falsy tests (!err). We found 4 non-critical discrepancies
among novacore and libraries. Possibly due to an older
JavaScript version, bun.js was slightly slower
than node.js.
