Except Javascript isn't assembly, no matter how much the author would like to think so. It's a reasonably well featured, multi-paradigm high-level language.

you might consider going back to slashdot. i didn't miss his point at all, try reading my comment again, but this time, try to read the statement "but Javascript isn't assembly" a little less literally.
