javascript - What is the simplest way to compare two arrays in QUnit -

i'm writing javascript unit tests (with qunit library). need verify array contains expected (and only) elements.

var array = getarrayfunction(a, b); equal(["one", "two", "three"], array, "test failing if 'array' contains needed elements"); 

what easiest way this?

you need use deepequal() in lieu of equal(). compare array elements , object properties, not use == comparison operator, evaluates false objects don't share same constructor.

docs here: https://api.qunitjs.com/deepequal/
