So, no language worth it's salt completely hides how the computer works from you (again, except for certain members of the FP family, or declarative languages like Prolog or SQL).

For example, Javascript has a problems when adding ".1+.2". Know why? IEEE754 limitations on double-precision floating-point arithmetic, as implemented in hardware.

Programming languages exist to program the machine, full stop. Everything else is just people faffing about on their thesis defense.

Anyways, if you didn't like Elixir--probably because you don't have the experience yet to see why it's awesome--that's okay: learn C. :)
