| - `time.sleep()` is no-op. Use `asyncio.sleep()` instead. This is a restriction from Pyodide runtime. See https://github.com/pyodide/pyodide/issues/2354. The following section about top-level await may also help to know how to use async functions on stlite. | ||
| - `st.experimental_data_editor` does not work as it relies on PyArrow, but it doesn't work on Pyodide. Track this issue on https://github.com/whitphx/stlite/issues/509. | ||
| - For URL access, `urllib` and `requests` don't work on Pyodide/stlite, so we have to use alternative methods provided by Pyodide, such as [`pyodide.http.pyfetch()`](https://pyodide.org/en/stable/usage/api/python-api/http.html#pyodide.http.pyfetch) or [`pyodide.http.open_url()`](https://pyodide.org/en/stable/usage/api/python-api/http.html#pyodide.http.open_url). See https://pyodide.org/en/stable/usage/faq.html#how-can-i-load-external-files-in-pyodide for the details. For `pyodide.http.pyfetch()`, see also the following section about top-level await. | ||
| - The C extension packages that are not built for Pyodide cannot be installed. See https://pyodide.org/en/stable/usage/faq.html#micropip-can-t-find-a-pure-python-wheel for the details. |

nit: maybe add something like:
st.bokeh_chartdoes not work since Pyodide uses Bokeh version 3.x while Streamlit only supports 2.x. The 3.x support for Streamlit is tracked here: Support bokeh 3.0.3 streamlit/streamlit#5858- There are some small differences in how (less common) data types of DataFrame columns are handled in
st.dataframe,st.data_editor,st.table, and Altair-based charts. The reason is that stlite uses the Parquet format instead of the Arrow IPC format to serialize dataframes.

Thanks! I added the second one in this PR, and will do the first one in another PR.
