/**
* Returns the result of concatenating the given lists or strings.
*
* Note: `R.concat` expects both arguments to be of the same type,
* unlike the native `Array.prototype.concat` method. It will throw
* an error if you `concat` an Array with a non-Array value.
*
* Dispatches to the `concat` method of the first argument, if present.
* Can also concatenate two members of a [fantasy-land
* compatible semigroup](https://github.com/fantasyland/fantasy-land#semigroup).
*
* @func
* @memberOf R
* @since v0.1.0
* @category List
* @sig [a] -> [a] -> [a]
* @sig String -> String -> String
* @param {Array|String} firstList The first list
* @param {Array|String} secondList The second list
* @return {Array|String} A list consisting of the elements of `firstList` followed by the elements of
* `secondList`.
*
* @example
*
* R.concat('ABC', 'DEF'); // 'ABCDEF'
* R.concat([4, 5, 6], [1, 2, 3]); //=> [4, 5, 6, 1, 2, 3]
* R.concat([], []); //=> []
