Emscripten Platform Information
===============================

"Pyodide" vs "Emscripten Python"
--------------------------------

For the sake of this document, we use the term "Emscripten Python" to refer to
the Emscripten Python maintained in the ``python/cpython`` repository, without
any downstream additions. We contrast the features present in Emscripten Python
to the features present in Pyodide.

Pyodide is maintained `on GitHub <https://github.com/pyodide/pyodide>`__ and
distributed via `jsDelivr <https://www.jsdelivr.com/oss-cdn/pyodide>`__, `npm
<https://www.npmjs.com/package/pyodide>`__, and `GitHub releases
<https://github.com/pyodide/pyodide/releases>`__.

Emscripten Python is not distributed, but it is possible to build `by following
the instructions in the devguide
<https://devguide.python.org/getting-started/setup-building/#emscripten>`__

mapping between the JavaScript object model and the Python object model and a
calling convention that allows high level bidirectional integration.
