/**
|
|
* Returns a function of arity `n` from a (manually) curried function.
|
|
* Note that, the returned function is actually a ramda style
|
|
* curryied function, which can accept one or more arguments in each
|
|
* function calling.

* @func
|
|
* @memberOf R
|
|
* @since v0.14.0
|
|
* @category Function
|
|
* @sig Number -> (a -> b -> c ... -> z) -> ((a -> b -> c ...) -> z)
|
|
* @param {Number} length The arity for the returned function.
|
|
* @param {Function} fn The function to uncurry.
|
|
* @return {Function} A new function.
|
|
* @see R.curry, R.curryN
|
|
* @example
|
|
*
|
|
* const addFour = a => b => c => d => a + b + c + d;
|
|
*
|
|
* const uncurriedAddFour = R.uncurryN(4, addFour);
|
|
* uncurriedAddFour(1, 2, 3, 4); //=> 10
