+/**
+ * Wraps a function of any arity (including nullary) in a function that accepts
+ * exactly `n` parameters. Any extraneous parameters will not be passed to the
+ * supplied function.
+ *
+ * @func
+ * @memberOf R
+ * @since v0.1.0
+ * @category Function
+ * @sig Number -> (* -> a) -> (* -> a)
+ * @param {Number} n The desired arity of the new function.
+ * @param {Function} fn The function to wrap.
+ * @return {Function} A new function wrapping `fn`. The new function is guaranteed to be of
+ *         arity `n`.
+ * @see R.binary, R.unary
+ * @example
+ *
+ *      const takesTwoArgs = (a, b) => [a, b];
+ *
+ *      takesTwoArgs.length; //=> 2
+ *      takesTwoArgs(1, 2); //=> [1, 2]
+ *
+ *      const takesOneArg = R.nAry(1, takesTwoArgs);
+ *      takesOneArg.length; //=> 1
+ *      // Only `n` arguments are passed to the wrapped function
+ *      takesOneArg(1, 2); //=> [1, undefined]
+ * @symb R.nAry(0, f)(a, b) = f()
+ * @symb R.nAry(1, f)(a, b) = f(a)
+ * @symb R.nAry(2, f)(a, b) = f(a, b)
