@jaissica12
what happens when you call hashAttributes on a value that's an arry using the Rokt SDK? we want to make sure the behavior is the same. something to flag to Matt if it's doing it improperly there

[jaissica12]

@rmi22186 In Rokt SDK when an array is passed for hashing, it is converted to a string using JavaScript String() coercion, which joins array elements with commas and then hashes them.

Example:

• Input: { favorite_colors: ['blue', 'green'] }
• String(['blue', 'green']) → 'blue,green'
• Calls hashString('blue,green') → SHA256 hash
• Output: { favorite_colorssha256: '' }

@mattbodle So as of now, both the Core SDK and the Rokt SDK allow hashing of arrays by implicitly converting them to strings. I’ve created this PR in core sdk to skip hashing when the value is an array.
Do we want to officially support hashing arrays, given that it currently just converts the array to a comma-separated string before hashing?
