JavaScript: Tips of the Day

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.


const tips_bifurcateBy = (arr, fn) =>
  arr.reduce((acc, val, i) => (acc[fn(val, i) ? 0 : 1].push(val), acc), [[], []]);
console.log(tips_bifurcateBy(['little', 'bo', 'peep', 'foo' ], x => x[0] === 'b'));


[["bo"], ["little", "peep", "foo"]]
