intersectionBy

_.intersectionBy(iteratee, arrays, arrays) # Ⓢ [Ⓣ][1] Ⓝ

This method is like _.intersection except that it accepts iteratee



which is invoked for each element of each arrays to generate the criterion



by which they're compared. The order and references of result values are



determined by the first array. The iteratee is invoked with one argument:



(value).

Since​

4.0.0

Arguments​

  1. iteratee (Function): The iteratee invoked per element.
  2. arrays (Array): The arrays to inspect.
  3. arrays (Array): The arrays to inspect.

Returns​

(Array): Returns the new array of intersecting values.

Example​

_.intersectionBy(Math.floor, [2.1, 1.2], [2.3, 3.4]);
// => [2.1]

// The `_.property` iteratee shorthand.
_.intersectionBy('x', [{ 'x': 1 }], [{ 'x': 2 }, { 'x': 1 }]);
// => [{ 'x': 1 }]
