Some people don't know that ECMAScript has only one Number type, and
your remark might have misled other into thinking otherwise, so I think
more explanation is helpful.  That's all.

Sure, but personal definitions of terms that have a technical meaning in
a particular language are often more confusing than helpful.  If you
like to think of Number variables that contain the floating point
representation of a whole number as having "integer type" that's fine,
but it's almost certainly going to be pointed out that you are not using
the standard meaning.
