Determine if two arrays are similar

/**
* =====================================================
* In the index.html file, write the Arrayssimilar function to determine if the two incoming arrays are similar. Specific requirements:
* 1. The member types in the array are the same, and the order can be different. For example [1, True] is similar to [FALSE, 2].
* 2. The length of the array is consistent.
* 3. The type of judgment range that needs to be distinguished: String, Boolean, number, undefined, null, function, date, window.
*
* When all of the above are satisfied, then return "decision Result: Pass", otherwise return "decision Result: Do not pass".
* =====================================================
