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 uniqueness is computed. The iteratee is invoked with one argument: (value).
_.intersection
iteratee
arrays
Optional
The iteratee invoked per element.
Returns the new array of shared values.
