Matching ifferent forms of nested JS object / array data matching

I have the results of my MongoDB db query for two variables as follows :

foodelectricity [
  { food: 'dairy', electricity: 1 },
  { food: 'fruitAndVeg', electricity: 1 },
  { food: 'grains', electricity: 1 },
  { food: 'bakedGoods', electricity: 5 },
  { food: 'protein', electricity: 1 }
]

foodresults { bakedGoods: 1, dairy: 3, fruitAndVeg: 1, grains: 2, protein: 1 }

I need to multiyply the number values in foodresults times the electricity associated with that same item type in food electricity.

For example :

let helpValue = foodresults.bakedGoods = 1 * foodElectricity.food.bakedGoods = 5.

I not believe that MongoDB returns the array in the same order each time -- so some sort of key value matching is required.

I am having trouble figuring out how to find the helpValue.

Any help is deeply appreciated.

With thanks Karen

What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
