Example

var objects = [
  { x: 1, y: 2 },
  { x: 2, y: 1 },
];
var others = [
  { x: 1, y: 1 },
  { x: 1, y: 2 },
];

_.intersectionWith(
  objects,
  others,
  _.isEqual
);
// => [{ 'x': 1, 'y': 2 }]

var objects = [
  { x: 1, y: 2 },
  { x: 2, y: 1 },
];
var others = [
  { x: 1, y: 1 },
  { x: 1, y: 2 },
];

_.intersectionWith(objects, others, _.isEqual);
// => [{ 'x': 1, 'y': 2 }]
