Lodash: Problem with _.difference

[dengyaolong]

I want to the set difference arrayA - arrayB , but when the arrayA include array, it does not work.
e.g

console.log(_.difference([[1]],[[1]]));
// -> [[1]] ,not []

I see samevalueszero http://ecma-international.org/ecma-262/6.0/#sec-samevaluezero
seems like Return true if x and y are the same Object value. Otherwise, return false.
We alwasy compare two arrays use Array.toString() and compare the string

var arrayA = [1], arrayB = [1];
arrayA.toString() === arrayB.toString() // true
arrayA == arrayB //false;

How can i get the difference in that times?

Do you actually want the difference or to compare two objects for equivalence?

This is coming in v4 as _.differenceWith(array, other, _.isEqual).
