Build a Symmetric Difference Function

Compare two arrays and return a new array with any items only found in one of the two given arrays, but not both. In other words, return the symmetric difference of the two arrays. Example: - Array A: `["diamond", "stick", "apple"]` - Array B: `["stick", "emerald", "bread"]` Result: `["diamond", "apple", "emerald", "bread"]` **Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab. **User Stories:** 1. Your function `diffArray` should return an array. 2. Your function should take two arguments, both of which are arrays. 3. Your function should make use of the `filter` method. 4. Your function should return the symmetric difference of the two arrays. 5. Your function should return an empty array if there is no symmetric difference.
