const remove = (arr, func) =>
  Array.isArray(arr)
    ? arr.filter(func).reduce((acc, val) => {
      arr.splice(arr.indexOf(val), 1);
      return acc.concat(val);
    }, [])
    : [];

remove([1, 2, 3, 4], n => n % 2 === 0); // [2, 4]

Removes elements from an array for which the given function returns false. Use Array.prototype.filter() to find array elements that return truthy values and Array.prototype.reduce() to remove elements using Array.prototype.splice(). The func is invoked with three arguments (value, index, array).
