The way I understood the OP's question was that he had correctly,
following the error message, converted to using numbers instead of
strings, but then didn't understand the obtained result.

This is interesting, nice.  I come from a background where numerical
precision and memory layout is often a concern (e.g. physics
simulations, hardware readout), but these types of things I think can
be more easily forgotten when using higher level languages like
javascript, python, etc.  Imo it's still an essential understanding to
have.
