# modular-exponentiation - a Pyodide demonstration

This is a simple single-page site that uses

[Pyodide](https://pyodide.org/en/stable/) to do big-integer modular

exponentiation with

[`pow`](https://docs.python.org/3/library/functions.html#pow), by running a

Python interpreter in the user’s browser via WebAssembly.

The goal is to be a very simple Pyodide demonstration. This is not really a

reasonable way to do modular exponentiation, other than for demonstration

purposes, since Pyodide is overkill for that. (It takes several seconds to

load, and modular exponentiation can be implemented on JavaScript bigints with

a straightforward recursive function.)

## Bugs

In Firefox, reloading the page repeatedly in the same tab (without navigating

away) will—usually gradually—use up more and more memory that is

not freed until the tab is closed. This seems like it may be a bug in Firefox

itself, but the result is that Pyodide cannot always load.

modular-exponentiation’s own user interface should, but does not yet,

detect this situation and inform the user of what to do.

The workarounds are to close the tab and reopen the site in a new tab, which is

usually sufficient, or to close Firefox altogether and reopen it if that does

not work.
