/**
* Returns the empty value of its argument's type. Ramda defines the empty
* value of Array (`[]`), Object (`{}`), String (`''`),
* TypedArray (`Uint8Array []`, `Float32Array []`, etc), and Arguments. Other
* types are supported if they define `<Type>.empty`,
* `<Type>.prototype.empty` or implement the
* [FantasyLand Monoid spec](https://github.com/fantasyland/fantasy-land#monoid).
*
* Dispatches to the `empty` method of the first argument, if present.
*
* @func
* @memberOf R
* @since v0.3.0
* @category Function
* @sig a -> a
* @param {*} x
* @return {*}
* @example
*
* R.empty(Just(42)); //=> Nothing()
* R.empty([1, 2, 3]); //=> []
* R.empty('unicorns'); //=> ''
* R.empty({x: 1, y: 2}); //=> {}
* R.empty(Uint8Array.from('123')); //=> Uint8Array []
