21 | * Returns the result of concatenating the given lists or strings.
|
22 | *
|
23 | * Note: `R.concat` expects both arguments to be of the same type,
|
24 | * unlike the native `Array.prototype.concat` method. It will throw
|
25 | * an error if you `concat` an Array with a non-Array value.
|
26 | *
|
27 | * Dispatches to the `concat` method of the first argument, if present.
|
28 | * Can also concatenate two members of a [fantasy-land
|
29 | * compatible semigroup](https://github.com/fantasyland/fantasy-land#semigroup).

35 | * @sig [a] -> [a] -> [a]

36 | * @sig String -> String -> String
|
37 | * @param {Array|String} firstList The first list
|
38 | * @param {Array|String} secondList The second list
|
39 | * @return {Array|String} A list consisting of the elements of `firstList` followed by the elements of

42 | * @example
|
43 | *
|
44 | * R.concat('ABC', 'DEF'); // 'ABCDEF'

45 | * R.concat([4, 5, 6], [1, 2, 3]); //=> [4, 5, 6, 1, 2, 3]
