Question posted in 
I have a JSON and I need to get SKU attribute value as a result array. The SKU attribute will be inside of shipping and OFSUC arrays. So I am trying to get those values efficiently using a filter or map function in JS but I don’t know how to iterate more than one array.
My JSON Object
