_.differenceBy(array, [values], [iteratee=_.identity])
This method is like _.difference
except that it accepts iteratee
which
is invoked for each element of array
and values
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).
Note: Unlike _.pullAllBy
, this method returns a new array.

Example
_.differenceBy(
[2.1, 1.2],
[2.3, 3.4],
Math.floor
);
// => [1.2]
// The `_.property` iteratee shorthand.
_.differenceBy(
[{ x: 2 }, { x: 1 }],
[{ x: 1 }],
"x"
);
// => [{ 'x': 2 }]
_.differenceBy([2.1, 1.2], [2.3, 3.4], Math.floor);
// => [1.2]
// The `_.property` iteratee shorthand.
_.differenceBy([{ x: 2 }, { x: 1 }], [{ x: 1 }], "x");
// => [{ 'x': 2 }]
