This is true. Value of a function 'f' is not its return value (there is none without parameter), but the code which defines its behaviour. You can do alert( f ) to see how javascript treats function values. > > To me a constant function is f(x) = x^0, since it's always equal to 1. This is a function which returns constant value (constant in space of floating point values). The return value is not the value of function in function space, the value in function space is the code which defines its behaviour. And in this space IDENTITY is constant - there is only one. alert( Funtion.IDENTITY ) shows you the value, and this value is constant in space of function values. This is one special function value - it corresponds to function which returns its parameter, and because of that this constant value deserves a name (unlike other constant function values, for which we do not have a name). izidor > > -- joneff > > On Oct 21, 12:44 pm, Izidor Jerebic <ij.l...@gmail.com> wrote: >> I beg to differ.
