Can someone explain to me like a child what makes JavaScript more "functional" than any of the many, many, many other languages that offer anonymous code blocks? kthnx.
I suspect that the audience for these slides is Javascript programmers, which is why JS is heavily emphasized.
I think lambda functions is the only truly FP feature Javascript provides, but it's so darn useful that it really should be emphasized. Lately, I can't stand writing in languages that don't provide lambda functions (like PHP pre-5.3, or current Java), so at least Javascript has that going for it.
