/**
* `chain` maps a function over a list and concatenates the results. `chain`
* is also known as `flatMap` in some libraries.
*
* Dispatches to the `chain` method of the second argument, if present,
* according to the [FantasyLand Chain spec](https://github.com/fantasyland/fantasy-land#chain).
*
* If second argument is a function, `chain(f, g)(x)` is equivalent to `f(g(x), x)`.
*
* Acts as a transducer if a transformer is given in list position.
*
* @func
* @memberOf R
* @since v0.3.0
* @category List
* @sig Chain m => (a -> m b) -> m a -> m b
* @param {Function} fn The function to map with
* @param {Array} list The list to map over
* @return {Array} The result of flat-mapping `list` with `fn`
* @example
*
* const duplicate = n => [n, n];
* R.chain(duplicate, [1, 2, 3]); //=> [1, 1, 2, 2, 3, 3]
*
* R.chain(R.append, R.head)([1, 2, 3]); //=> [1, 2, 3, 1]
