Creating an array iterating all the objects in an array of object

Question

I have this JSON structure, I want to create 2 arrays out of this array of JSON. one array having all the values from key "employee only" to ""Annual OOP max / entire famliy" (from each object in JSON array) and 2nd array to have values from key "Primary care doctor visit" to end of the object".

array 1 = [86.1,30.5,33.2, 291.3, 154.1, 121.2..............13700, "$13,100 family"] (so for eg "employee only" key from object1 then object2 then till last object, again next key from object 1...till last object)

similarly in array 2 starting from key "Primary care doctor visit" till end of object

array 2 = ["75% covered after deductible", "$35 copay",35,............, "See HMO provider"]

How can i achieve this in javascript?

Create an Array with some of the values, check something like Object.entries to explore the Objects within the Array and play around with it. — KooiInc

Does this answer your question? How to create a new array out of array of objects? — James Z

I don't really see what is the difference in your questions. Please don't post duplicate questions like that and if there is a difference then refer to your previous question and explain what is different — James Z
