Iterate and sum two different array of objects and return new array- JS

Question

Is that possible to sum two different objects from array object and to return single array of object?

let source= [{
  "supplimentKing": [{
    "pwdrName": "zzzzz",
    "pwdrPrice": "2"
  }],
  "protinsAddonOffer": [{
    "pwdrName": "oooo",
    "pwdrPrice": "3"
  }]
}];

result:

[{
  "pwdrName": "zzzzz + oooo",
  "pwdrPrice": "5"
}]

After trying to understand similar SO 1 , SO 2, SO 3 i could not understand how to get expected result.

could some one pls help me how to sum the properties in clean way?

Thanks

You want to merge all the objects in the array to a single value/object ? — Nithish

This just needs a for loop and parseInt() - So what have you tried so far to solve this on your own? — Andreas

You could use reduce to add values

let source= [{
  "supplimentKing": [{
    "pwdrName": "zzzzz",
    "pwdrPrice": "2"
  }],
  "protinsAddonOffer": [{
    "pwdrName": "oooo",
    "pwdrPrice": "3"
  }],
  "proAddonOffer": [{
    "pwdrName": "iiiii",
    "pwdrPrice": "3"
  }]
}];

p=[]
  source.forEach((o)=>{
    p.push(...Object.values(o))
  })
  v=p.flat()
total= v.reduce((acc,curr)=>{
  acc= [{"pwdrName":curr.pwdrName+"+"+acc.pwdrName,"pwdrPrice":Number(curr.pwdrPrice)+Number(acc.pwdrPrice)}]
  return acc[0]

})
console.log([total])
