+### bifurcate
+
+Splits values into two groups. If an element in `filter` is truthy, the corresponding element in the collection belongs to the first group; otherwise, it belongs to the second group.
+
+Use `Array.reduce()` and `Array.push()` to add elements to groups, based on `filter`.
+
+```js
+const bifurcate = (arr, filter) =>

+### bifurcateBy
+
+Splits values into two groups according to a predicate function, which specifies which group an element in the input collection belongs to. If the predicate function returns a truthy value, the collection element belongs to the first group; otherwise, it belongs to the second group.
+
+Use `Array.reduce()` and `Array.push()` to add elements to groups, based on the value returned by `fn` for each element.
