How this page works. pyfuse runs as real CPython compiled to WebAssembly (Pyodide) — the results above are computed by the same wheel you would pip install. When compare with fuse.js is on, the original library is loaded separately and given identical input, purely as an oracle to diff against. The published Python package contains no JavaScript and never calls one; this pairing exists only here and in the project's test harness.
