JavaScript Implementation of function currying - By adding a curry method to the Function prototype

curry.js

Function.prototype.curry = function( ) {
	var slice = Array.prototype.slice,
		self = this,
		totalargs = self.length,
		partial = function( args, fn ) {
			return function( ) {
				return fn.apply( {}, args.concat( slice.call( arguments ) ) );
			}
		},
		fn = function( ) {
			var args = slice.call( arguments );
			return ( args.length < totalargs ) ?
				partial( args, fn ) :
				self.apply( {}, slice.apply( arguments, [ 0, totalargs ] ) );
		};
	return fn;
};

Hello, Nice implementation. I want to understand why have you used slice.call( arguments ) instead of arguments.slice(). Is it because arguments does not have slice but the implementation of slice is such that it works with the arguments object. One more question, How is the value of arguments decided? In nested functions, will the arguments have the arguments of it immediate wrapping function? Thank you

the arguments is a array-like object, there is no slice in it.
