Jeffrey and Glen,
Allow me to explain currying. Imagine if you will the following function
(written in javascript)
add = function (a,b) { return a+b }
I can now call add(3,7) and it will return 10.
A language that allows currying would allow me to pass only one variable and
it would return a new function that takes a single variable. ex:
add(3)would return a function that adds three to the input. Here is an
example way
of implementing it in javascript:
add = function (a) { return function (b) { return a+b } }
Now I can call add(3) and it will return function (b) { return 3+b }
In the same sense as the first example we can now call add(3)(7) and it will
return 10.
This allows for lots of cleverness in use of functions and ultimately make
functions far more reusable. I consider it a great advantage of functional
programming. So as you can see, the same effect can be created, but it's
tedious. I'm trying to come up with a trickier way so that it's not so
painful to create a curried function in javascript.
